Google cheapassgamer and you'll find the trade-in values there. Also gamestop has a lot of good trade-in deals right not. Go to there website gamestop.com
Do not sell to gamestop man! they pay rediculously low for their games! Sell them on either ebay or craigslist, or see if any friends or family want to buy them. You can get a lot more money that way than selling them to gamestop. If they buy them from you, than it means that they think they can easily make more. trust me man, that would be a mistake. hope this helped!How much money will i get when i trade in games at gamestop?
I just traded in Black Ops for 36 BUCKS!!!! but i Had a power up rewards card. Cod 4 you probably won't get crap for and mw2 im guessing between 12-15.
For Ps3/Xbox360 games probably $12-$15 a game.How much money will i get when i trade in games at gamestop?
