Game Prices - Anyone else notice this...

[QuickStop]

even though you aren't really supposed to, I have returned a few pc games to best buy. If i didnt like the game, or i beat it, i just put that little sticker back on and tell them it was a birthday gift and i already have the game. one time, i actually had to construct a makeshift sticker using scotch tape and a razor blade to cut it into a circular shape.
