I'm about to sell a PS3 game on Ebay. I would like to allow returns because the game isn't in the best condition it could be and I want my potential customer to be as satisfied as possible. But, I don't want to get ripped off by someone returning a different disc (that could be in worse condition) of the same game. Is there any way to distinguish different copies of the same game? Is the number on the inner most ring on the data side unique? If so what is that number called?
