Even though the holidays come around the same time each year, it’s so easy to let the month of December pass you by. All of a sudden, there are only a few days before Christmas left and you realize you don’t have any gifts for anyone! Oops.

Luckily, stores and delivery companies understand the last-minute gift-buying struggle (you’re certainly not alone) and are willing to put in the extra effort to help.

A few retail chains, plus FedEx, UPS and more, have recently unveiled a list of their shipping deadlines—aka when’s the last day you can order by to have a gift arrive by Christmas is.
