Game and Movie Traders Attempted to Exchange Game and was told the.game was 59.99 when it retailed new for 40.00 Mineral Wells Texas

I attempted to go into the local game and move trader's store today to purchase a video game called Diablo Three Ultimate Evil editon and also to trade in another game for the xbox one. I was told with my tradein value that they would match Gamestop plus add extra on top of what they offered.  Battlefield Hardline trades in for $33.00 as of 4/23/2015 and I was only offered $30.00 Now while the trade in was not  really the problem the Game that I mentioned above sells new on Gamestop.com For $40.00 and the pre owned copy for $33.00. They attempted to sell me the pre owned copy of the game for $51.00. The game disk appereared to be scratched and the case of the game appeared to be sunken in.
