I thought the boxes they put on display was just that: for display purposes.  You take the box to the counter and they give you a brand new (unopened) game.  It's silly to have them give you the discs for the box, and then open another new one to put the box on display.  I don't know.  The more I hear about their practices, the less I want to buy from them.
