lol I wonder what price you expect when a relatively new game gets traded in. 20 bucks used if its still 60 new? lol Usually when new games come out, its automatically worth HALF of what it's new price is. If it's a crappy, not so popular game, of course you'll get less, and it'll be cheaper used. It all depends on the popularity of the game and how many is traded in to gamestop.
If it's a hard to find game at gamestop, of course you'll get moer for it, and of course it'll be pretty expensive.. lol
Most of you that have grudges against gamestop and other video game retailers are usually the idiots who don't read the receipt on return policies, etc.
