We’ve re-launched our Ars Technica merch store just in time for the holidays, and the response has been great—”Nuke it from orbit” mugs and Ars hyperspace logo T-shirts are flying off the virtual shelves.

If you’re pondering an order and want to make sure it arrives by Christmas, order today to avoid disappointment. Between the time needed to print the shirts and the time needed to ship them, December 11 is the final day to place most orders for Christmas delivery. Here are the shipping options that will still get your merch to you by December 25:

USPS Priority Mail: Dec 11
FedEx 2 Day: Dec 11
FedEx International Priority: Dec 11
FedEx Standard Overnight: Dec 12
