I quit shopping at Gamestop because they opened many of their boxes. Since they are selling new games along with used for consoles, how do you know which you will end up with? Case in point, I purchased a Nintendo DS game for my daughter. Christmas Day when she opened it up and put it in her DS there were saved games on it already - it had obviously been used. When I bought it, I mentioned that the box was not sealed, and they claimed that they had to do that else they would get shoplifted. I replied that other stores have less employees in the store but don't have their games opened and behind the counter.
Another time in a different Gamestop my son bought the PS2 game Devil May Cry, again the package was open and the had the discs behind the counter. A few days later while playing it asks him to insert Disc 2, which was not in the box. We went back to the store and they still had the 2nd disc.
In both cases they made good, but after those experiences they lost me as a customer, and I had been shopping there nearly every week since they were Babbages. It sounds like they have still haven't learned not to open packages.
In this case it's even worse - don't they have to break the security seal to get the coupon? In the old days they could just re-shrink wrap it, these days most games come with a security seal as well.
