Shit man, I stopped going to gamestop when the Orange Box came out and they sold me a used copy with all the CD keys for portal/halflife/tf2 used TWICE in one day. Not set a fuckin' foot in there since.
Last time I bought something at GameStop it was a PSN card that was already used. They tried to blame me saying I used it and was trying to swindle them out of a free card. Stopped going there ever since.
