i would say ebay..the reason why, is that game stop is really good at ripping you off when you trade things in... the game spider man, might get 4 bucks at game stop.. while on ebay 15.. definitely try ebay first and then gamestop.Which is better selling 9 ps2 games on ebay together or trading them into gamestop?
try http://www.goozex.com/trading/asp/join.asp?refcode=US-4231406-20081229 It's like gamestop and is online and doesn't rip u off. I have been using this website for months and the trade value is based on it's REAL value. Gamestop should be your last choice to trade games to.
