I am going to trade in Forza 2 to my local blockbuster. Problem is that it is the version of the game that was packaged with the 360 premium (so it says not for resale on the front and on the back where the UPC should be). My blockbuster will only take games that have cases so just trading in the disc isn't an option. Is there any way i could cover up the "not for resale" without them getting suspicious? I am thinking about cutting out the not for resale on the back and hope they don't notice the front one.
