people are really good at shrink wrapping back to like new form and returning the games. Usually the people at returns are too lazy to open the game and just put it back on the shelf..got burned once in the 90's on a wu tang cd this way. inside was a aol free trial cd
I wonder how many of the stores that open plastic wrapped itms to verify content have the ability to re wrap them? My perception is that once it's opened, it can't be sold as new unless it's rewrapped.
