It’s the Cyber Monday deal I didn’t see coming: The new Nintendo Switch 2 with Mario Kart World bundle is actually discounted today, which is surprising considering there’s no real incentive to knock money off a brand new system, and because it was not discounted at all during Black Friday.

But yes, at the moment, you can get the game and system for $449 (down from $499) at both Amazon and Walmart—the lowest price it has reached yet, according to price tracking tools. (Note that you can only see the price once it’s in your cart as Nintendo restricts retailers from promoting anything below the “minimum advertised price” of $499.) With Christmas on the way, this deal is likely to sell out fast, so I’ve advise ordering it sooner rather than later if you’re considering it.

To put into perspective how good this deal is, the OLED edition of the original Nintendo Switch is $400 right now, meaning you can get the new system and a great game for only $50 more—and the Switch 2 is an upgrade in every way, according to Lifehacker’s review. You can play your old Switch games on the Switch 2, since it’s backwards compatible. The ergonomics and design have improved, making it much better to hold and look at. The battery life has also improved, now with about 180 minutes of handheld playtime before the juice runs out.

The biggest thing to consider when deciding whether you should buy a Switch 2 right now is that the library is currently on the smaller side, with few absolute must-play titles yet released (and the ones that are out may cost more, going up to $80). But being able to play your older games does make the transition easier, especially considering some games, like The Legend of Zelda: Tears of the Kingdom, will look better on the Switch 2.

Does Amazon have Cyber Monday deals?

Yes, Amazon has Cyber Monday sales, but prices aren’t always what they seem. Use a price tracker to make sure you’re getting the best deal, or refer to guides like our live blog that use price trackers for you. And if you have an Amazon Prime membership, make the most of it.

What stores have the best sales on Cyber Monday?

Nowadays, both large retailers and small businesses compete for Cyber Monday shoppers, so you can expect practically every store to run sales through Monday, December 1, 2025. The “best” sales depend on your needs, but in general, the biggest discounts tend to come from larger retailers that can afford lower prices: think places like Amazon, Walmart, Target, Best Buy, and Home Depot. You can find all the best sales from major retailers on our live blog. 

Are Cyber Monday deals worth it?

In short, yes, Cyber Monday still offers discounts that can be rare throughout the rest of the year. If there’s something you want to buy, or you’re shopping for gifts, it’s a good time to look for discounts on what you need, especially tech sales, home improvement supplies, and fitness tech. Of course, if you need to save money, the best way to save is to not buy anything. 

It’s been over 10 years since the launch of the excellent The Witcher 3: Wild Hunt, and nearly four years since the announcement of “the next installment in The Witcher series of video games.” Despite those long waits, developer CD Projekt Red is still insisting it will deliver the next three complete Witcher games in a short six-year window.

In a recent earnings call, CDPR VP of Business Development Michał Nowakowski suggested that a rapid release schedule would be enabled in no small part by the team’s transition away from its proprietary REDEngine to the popular Unreal Engine in 2022. At the time, CDPR said the transition to Unreal Engine would “elevate development predictability and efficiency, while simultaneously granting us access to cutting-edge game development tools.” Those considerations seemed especially important in the wake of widespread technical issues with the console versions of Cyberpunk 2077, which CDPR later blamed on REDEngine’s “in-game streaming system.”

“We’re happy with how [Unreal Engine] is evolving through the Epic team’s efforts, and how we are learning how to make it work within a huge open-world game, as [The Witcher 4] is meant to be,” Nowakowski said in the recent earnings call. “In a way, yes, I do believe that further games should be delivered in a shorter period of time—as we had stated before, our plan still is to launch the whole trilogy within a six-year period, so yes, that would mean we would plan to have a shorter development time between TW4 and TW5, between TW5 and TW6 and so on.”

Normally $366.66, this 305-lb Olympic bumper plate set is currently on sale for $265.99 on Amazon—that’s over $100 off for Cyber Monday. Here’s the real kicker: You’re basically paying $1 per pound, which is a seriously good deal when it comes to at-home strength training.

What you get

This set includes everything you need to start serious barbell training at home:

• 1x 7-foot Olympic 2-inch barbell (45 lbs)

• 2x 10 lb plates

• 2x 15 lb plates

• 2x 25 lb plates

• 2x 35 lb plates

• 2x 45 lb plates

That’s 305 pounds total of equipment, giving you plenty of weight progression options whether you’re doing deadlifts, squats, bench press, or Olympic lifts.

Plus, unlike traditional iron plates, bumper plates are made of rubber. The rubber on these should minimize bouncing and protects your floors—crucial if you’re training in a garage or basement and don’t want to damage the surface (or annoy your neighbors).

Whether you’re building out a home gym from scratch or upgrading from cheaper plates that have seen better days, this Cyber Monday deal delivers serious value. At roughly $1 per pound, you’d be hard-pressed to find a better price on a complete Olympic bumper plate set with a barbell included.

How long do Black Friday deals really last?

Black Friday sales officially begin Friday, November 28, 2025, and run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. You can get the same Black Friday sales early, and we expect sales to wind down by December 3, 2025. 

Are Black Friday deals worth it?

Are Cyber Monday deals better than Black Friday?

Black Friday used to be bigger for major retailers and more expensive tech and appliances, while Cyber Monday was for cheaper tech and gave smaller businesses a chance to compete online. Nowadays, though, distinction is almost meaningless. Every major retailer will offer sales on both days, and the smart move is to know what you want, use price trackers or refer to guides like our live blog that use price trackers for you, and don’t stress over finding the perfect timing.

I can take or leave some of the things that Microsoft is doing with Windows 11 these days, but I do usually enjoy the company’s yearly limited-time holiday sweater releases. Usually crafted around a specific image or product from the company’s ’90s-and-early-2000s heyday—2022’s sweater was Clippy themed, and 2023’s was just the Windows XP Bliss wallpaper in sweater form—the sweaters usually hit the exact combination of dorky/cute/recognizable that makes for a good holiday party conversation starter.

Microsoft is reviving the tradition for 2025 after taking a year off, and the design for this year’s flagship $80 sweater is mostly in line with what the company has done in past years. The 2025 “Artifact Holiday Sweater” revives multiple pixelated icons that Windows 3.1-to-XP users will recognize, including Notepad, Reversi, Paint, MS-DOS, Internet Explorer, and even the MSN butterfly logo. Clippy is, once again, front and center, looking happy to be included.

Not all of the icons are from Microsoft’s past; a sunglasses-wearing emoji, a “50” in the style of the old flying Windows icon (for Microsoft’s 50th anniversary), and a Minecraft Creeper face all nod to the company’s more modern products. But the only one I really take issue with is on the right sleeve, where Microsoft has stuck a pixelated monochrome icon for its Copilot AI assistant.

Smart TVs have undoubtedly taken over the streaming space, and it’s not hard to see why. You download the apps you want to use, log into your accounts, and presto: You can stream anything with a few clicks of your remote.

But smart TV apps aren’t the only way people watch shows and movies on platforms like Netflix. Among other methods, like plugging a laptop directly into the TV, many people still enjoying casting their content from small screens to big screens. For years, this has been a reliable way to switch from watching Netflix on your smartphone or tablet to watching on your TV—you just tap the cast button, select your TV, and in a few moments, your content is beamed to the proper place. Your device becomes its own remote, with search built right-in, and it avoids the need to sign into Netflix on TVs outside your home, such as when staying in hotels.

At least it did, but Netflix no longer wants to let you do it.

Netflix no longer supports casting on most devices

While you can still cast to your TV from other streaming platforms, there’s bad news for Netflix fans: The company has abruptly dropped casting support for most devices. Android Authority was the first to report on the change, though you might have stumbled upon the development yourself when looking for the cast button in the Netflix app. In fact, Netflix has prepared for your confusion, as you can see from this Netflix Help Center page titled “Can’t find ‘Cast’ button in Netflix app.” This page might offer a glimmer of hope at first, as you think “Oh good, Netflix has a solution if the Cast button is missing.” Unfortunately, the response isn’t going to make you happy: “Netflix no longer supports casting shows from a mobile device to most TVs and TV-streaming devices. You’ll need to use the remote that came with your TV or TV-streaming device to navigate Netflix.”

The exception here is for “older” Chromecast devices or TVs that work with Google Cast—but only if you pay for an ad-free Netflix plan. If you took Netflix up on its lower-cost subscription offer, those ads not only cost you extra watch time, but also your ability to cast—assuming you even have the older hardware to cast to.

While Android Authority was the first major publication to report on the issue, some Netflix casters have been living with the change over the past couple of weeks. On Nov. 14, this user posted on the Chromecast subreddit voicing their complaints about the change. They were particularly frustrated with the lack of communication from Netflix, as the Cast button was removed “with zero warning.” Other users in the thread noted their frustrations, too, with some threatening to cancel their subscriptions over the issue.

Why is Netflix removing support for casting?

Netflix doesn’t explain why it’s making the change, so I can only speculate. First, it’s totally possible this is simply a tech obsolescence issue. Many companies drop support for older or underused technologies, and perhaps Netflix sees now as the time to largely drop support for casting. Streamlining the tech the app has to support means less work for Netflix developers, and it wouldn’t be the first time the company dropped support for older platforms. However, that doesn’t really explain why the company still supports some devices for casting. Maybe it took a look at its user base, and made the calculation that enough subscribers relied on Google Cast devices for casting, but not enough relies on newer hardware for casting. We might not really know unless Netflix decides to issue a statement.

That said, I can’t help but feel like this is related to Netflix’s crackdown on password sharing. The company clearly doesn’t want you using its services unless you have your own paid account—or have another user pay extra to have you on their account. Casting, however, makes it easy to continue using someone else’s account without paying for it. Since Netflix only requires mobile users to log into the account owner’s home wifi once a month to continue watching on a device, you could theoretically cast Netflix from your smartphone to your TV to continue enjoying your shows and movies “for free.” By removing casting as an option for most users, those users will either need to connect a device to the TV by wire—like a laptop connected via HDMI—or log into the smart TV app. And if those users don’t actually have permission to access that account via that app, they won’t be able to stream.

If this really is the company’s intention, it’s doing so at the inconvenience of paying users, too. If you’re traveling, you now need to bother with signing into your account on a TV you don’t own. If you don’t like using your smart TV apps, you’re kind of out of luck, unless you want to deal with connecting a computer to your TV whenever you want to catch up on Stranger Things.

How to fix Netflix casting issues with compatible hardware

If you do meet the new requirements for casting on Netflix, and the cast button still isn’t appearing, Netflix does have some troubleshooting steps you can take on its Help Center page. It’s device-dependent, but generally, here’s what you should do:

• Check your Chromecast’s wifi network: You can ensure your Chromecast is actively connected to your wifi network from the Google Home app on your iPhone or Android device.

• Turn your device off and on again: If you’re casting from your phone or tablet, power it off completely, then turn it back on again.

• Turn your Chromecast off and on again: If your device boots back up but the Cast button is still missing, power off and unplug your Chromecast for at least 15 seconds before turning it back on again.

• Sign out of Netflix: Log out of Netflix on the device you’re trying to cast from.

• Turn off Chrome extensions: If you’re using Chrome on a Mac or PC for casting, Netflix recommends turning off your browser extensions. (This seems like an extreme step in my opinion, especially if you’re someone who relies on Chrome extension—but if it works, it works.)

Telecom regulators in India have reportedly asked smartphone manufacturers to preload a state-owned cybersecurity app that cannot be deleted onto all new devices, and push the app to existing devices via a software update. Reuters reports that, according to a non-public government order sent to manufacturers, Apple, Samsung, Xiaomi and others were given 90 days to comply.

The app in question is called Sanchar Saathi (meaning Communication Companion), and is primarily aimed at fraud prevention with tools that allow users to report and lock lost or stolen devices. According to Reuters, the app has a reported 5 million downloads since its release and has helped block 3.7 million stolen or lost phones in India. An additional 30 million reportedly fraudulent connections have been terminated using the app.

“If I lose my phone, immediately the app is on my phone which I can then register and make sure my phone is not used by any fraudulent individual. It’s a step to protect the consumer,” Telecom Minister Shri Jyotiraditya M. Scindia said in an interview with CNBC. The Minister said the installation order should be issued in the “next couple of days.”

How smartphone manufacturers will respond remains to be seen. Apple, for its part, doesn’t have the strongest history of standing up to governments that oversee large markets for the company. Just a few weeks ago Apple removed two of the largest LGBTQ+ dating apps from the Chinese App Store at the government’s request. In 2019 the iPhone maker removed a Hong Kong protest app following pressure from Chinese authorities. The company has also become increasingly entangled with India as it looks to move US-bound iPhone production to the country.

The Santa Monica City Council has unanimously voted to order Waymo to halt overnight charging operations at two outdoor depots near Broadway and 14th Street after months of resident complaints about constant beeping from reverse sensors, noise from charging equipment, traffic congestion and flashing lights between 11 p.m. and 6 a.m. As many as 56 autonomous vehicles charge at the two sites. It’s unclear whether Waymo or its Virginia-based charging operator Volterra intends to comply.

The Los Angeles Times reported that neither company planned to, claiming city officials misunderstood their existing permit rights. Waymo told the newspaper it had adjusted operations in response to neighbor feedback and would continue seeking community input, though the company did not address the order directly. Local law enforcement has gotten involved after at least one person attempted to disrupt operations at the facilities on several occasions.

The dispute points to a broader challenge facing the autonomous vehicle industry: charging depots need to be close to service areas to minimize deadhead miles (distance traveled without revenue-generating passengers), but situating them in residential neighborhoods creates exactly these kinds of conflicts.

Marques Brownlee’s Panels app is shutting down on December 31. The creators blame this on a shifting development team, as they weren’t able to “bring in collaborators who shared our passion and vision, and we weren’t able to find the right fit.”

Annual subscribers will get a refund when the app shutters and any downloaded wallpapers will still be available to use. Additionally, the developers will be making the app’s code available to “allow anyone to build on what we started.”

Brownlee, a popular tech YouTuber who goes by MKBHD, introduced the Panels app back in 2024. It sailed to the top of the various app charts, for a time, but was mired by controversy. It’s basically just a marketplace for smartphone wallpaper images, but one that requires a steep subscription price for real access. Angry consumers also complained that the app was plagued by intrusive ads and mandated intrusive data-tracking permissions.

MKBHD tried to assuage concerns by introducing a cheaper subscription tier and improving the free experience. However, it looks like the damage was done. Panels was a tough sell even without the frustrations, as not that many people want to spend real money on smartphone wallpapers. Maybe that idea would’ve flown when smartphones were still new and exciting, but that ship sailed over a decade ago.

If you’ve been curious about smart rings but hesitant about the price, I’ve got great news: Normally $399.99, the Samsung Galaxy Ring is currently on sale for $249.95 for Cyber Monday.

As Lifehacker’s own Daniel Oropeza says, Samsung’s Galaxy Ring isn’t just a one-off experiment—it’s a well-made health-monitoring product. According to PCMag’s review, it’s a solid first-generation smart ring, though you’ll get the most out of it if you have a Samsung phone.

If you are already part of the Samsung ecosystem, this ring is great health and sleep tracker, monitoring metrics like heart rate, skin temperature, and sleep quality. However, if you’re looking for detailed activity tracking, you’re still better off with a smartwatch. This is more about passive health monitoring throughout your day and night.

Design and features

The Galaxy Ring comes with a titanium finish in gold, silver, and black. Like Oura rings, it’s a bit bulkier than a regular ring at 7mm wide and 2.6mm thick—something to consider if you’re not used to wearing jewelry.

Samsung users get extra perks: You can control your phone’s camera or dismiss alarms by tapping your ring finger to your thumb twice in a row. It’s a small touch, but these kinds of integrations make the device feel more seamlessly connected to your tech ecosystem.

No subscription required

Here’s the biggest advantage over the main competition: The Galaxy Ring is subscription-free. Oura rings require an ongoing monthly fee to access your health data, but Samsung gives you full access without additional costs. That alone could save you hundreds of dollars over the ring’s lifetime.

The ring is IP68 water resistant, so you can wash your hands and shower without worrying about it. It comes with a wireless charging case, and the battery lasts about six days per charge. Sizes range from five to 15, so most people should find a comfortable fit.

Bluetooth tracking tags are the perfect holiday gift; they’re both high-tech and practical, they’re easy to set up and use, and literally everyone has something they lose, from luggage, to laptops, to car keys, to pets. Plus, they’re compact and easy to wrap. Best of all, these Mate tags from Tile are —especially while they’re 50% off for Cyber Monday.

But that’s only half of what makes these trackers useful, because also work in reverse: You can click a Mate and it will ring your phone in case you lose that.

A four pack of Mate trackers for $39.99 is the lowest price Amazon has ever offered, so this isn’t an illusionary bargain, and it’s much cheaper than Apple’s competing product: A four-pack of AirTags lists for $99, and is currently on sale for $62.99.

Normally $295, the Core 2 Thermal Sensor is currently on sale for $236—a 20% discount for Cyber Monday. And here’s the smart play: buying it now means you’ll be ready to get ahead of the heat when spring training season rolls around.

Core 2 Thermal Sensor

$294.95

What the Core 2 does

The Core 2 is a small plastic sensor that attaches to your heart rate monitor chest strap and tracks your body temperature during workouts. It’s designed to help you understand how heat is affecting your performance, and guide you through heat-training protocols so you can adapt faster and more efficiently.

My colleague Beth Skwarecki reviewed the Core 2 and found it a little fussy to set up, but easy to use and understand once you’re up and running. What really impressed her was the big-picture view it provides: tracking how your body adapts to heat over time.

Train hot, race cool

The data from the Core 2 serves two main purposes. First, it can guide your heat acclimation training—helping you adapt to hot conditions more strategically. Second, you can use it during races to monitor your core temperature and avoid overheating when it counts.

As Beth points out, there’s a legitimate debate about whether heat training makes sense for every athlete. You could argue that most runners would benefit more from longer or faster runs rather than adding heat stress to their training. But if you are training in the heat—whether because you live somewhere hot, you’re preparing for a warm-weather race, or you’re intentionally pursuing heat adaptation—the Core 2 seems to be an incredibly useful tool.

Worth it for the right runner

At nearly $300, this isn’t an impulse purchase. But at $236, it’s more accessible for serious athletes who want to take their heat training to the next level. Getting it now during Cyber Monday means you’ll have months to familiarize yourself with the device before temperatures climb in spring and summer. By the time race season heats up, you’ll already know exactly how your body responds to thermal stress—and how to manage it.

In Amazon’s Cyber Monday 2025 sale, the Bose QuietComfort Headphones are down to $159.99 (54% off) in black. The best thing about these headphones are the color choices it’s available in, and the good news is that multiple color variants are going at $179.99 (50% off). That’s still a decent savings, even if it’s not quite as high as what you’d save on the more boring color.

PCMag’s review gave this product a 4/5, praising it for its controls, sound quality, and noise cancellation. This product misses out on support for newer Bluetooth codecs, unlike the pricier Bose QuietComfort Ultra ($399, 11% off). The older product doesn’t charge as fast as the QC Ultra either, but it will still sound great. The review calls out the price for being a bit too high, but this Cyber Monday Sale rectifies that. You can now get the QuietComfort headphones for $239 less than the QuietComfort Ultra.

I recently tried the QuietComfort headphones in-person, and I was impressed by the build quality and how light they felt on my head. The noise cancellation was also great.

These types of headphones serve a dual purpose in my life. They cut out external noise during long flights, and they also keep my ears warm when I’m in windy places in the winter (looking at you, Scotland!). If you’re not sure which over-ear headphones to get this Cyber Monday, look no further than the Bose QuietComfort ones.

How long do Cyber Monday deals really last?

Black Friday sales officially begin Friday, November 28, 2025, and run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. Expect sales to wind down by December 3, 2025. 

What stores have the best sales on Cyber Monday?

Nowadays, both large retailers and small businesses compete for Cyber Monday shoppers, so you can expect practically every store to run sales through Monday, December 1, 2025. The “best” sales depend on your needs, but in general, the biggest discounts tend to come from larger retailers that can afford lower prices: think places like Amazon, Walmart, Target, Best Buy, and Home Depot. You can find all the best sales from major retailers on our live blog. 

Are Cyber Monday deals worth it?

In short, yes, Cyber Monday still offers discounts that can be rare throughout the rest of the year. If there’s something you want to buy, or you’re shopping for gifts, it’s a good time to look for discounts on what you need, especially tech sales, home improvement supplies, and fitness tech. Of course, if you need to save money, the best way to save is to not buy anything.
