Christmas day has come to an end, which means Amazon's after-Christmas sale is officially live. That means you can cuddle up on the couch and browse for gifts you didn't get this year or spend an Amazon gift card you just received.

There are usually two types of people on Dec. 26: those who never want to open their wallet again and those who are still swept up by the holiday (spending) spirit (that post-Christmas aftershock can hit hard and fast) — but after-Christmas sales somehow temp both.
