When Comcast brought its gigabit cable Internet service to the Chicago area in August, it gave customers in some parts of Chicago and nearby towns the option of subscribing for $70 a month—half off the standard, no-contract price of $140.

Though the $70 gigabit offer required a three-year contract, it came with unlimited data, which normally costs an extra $50 a month on top of the $140 no-contract price. For Comcast customers, this was a good deal.

But Comcast didn’t make the $70 offer available throughout the Chicago area, and now the company has restricted it even further. The offer remains available in parts of Chicago, namely Uptown, Grand Crossing, the Loop, and South Loop.
