I understand that GameStop needs to make money, but there's no reason as to why they feel the need to rip off their customers.
I've brought in games before. Sure, they were used, what were they expecting; a brand new untouched game? Pffft, please. I must have brought 6 DS games and they only offered me $12 dollars... $12 dollars for games that cost about $20 dollars each. GameStop, that's beyond ridiculous. No wonder they have so many unsatisfied customers. :/
