[quote name='Tsukento']lol Seriously?
For starters, GameStop doesn't do price adjustments if a game drops in price after you've bought it. They're not like other retailers.
Second, you only have a week to return it for a refund. Once that time's up, you can't return it for a refund. Your only choice is to trade them in.[/quote]
Technically, you have 30 Days if Unopened for a full refund. However, if it's opened you can only get a defective swap for the same game, but that is also within 30 days.
7 Days for Opened Accessories or Used Games will get you a refund.
