GameStop has been accepting video game trade-ins for decades. Now they're letting customers trade in anything as long as it fits in a 20x20x20 box.

GameStop's new event allows trade-ins of almost any item that fits the size rules, expanding beyond traditional video game and console exchanges.

GameStop is doing a special “Trade Anything Day” which will allow you to trade in almost anything, but you may have some questions about what isn’t allowed, how much you can get, and what other rules and terms may apply.
