Misunderstanding, my bad dude, I didn't cop it from GameStop.
The magazine Best Buy just released, Gamer, has some coupons in it. One was for $20 off Bioshock 2, which is now $39.99 so I copped it from there brand new.
I think I posted that in a thread here somewhere (that was for the mag). Then the thread was deleted for some reason and re-made, but I didn't bother re-posting my post.
