I do not know why, but why do people always ask on boards for how much they're worth. I believe they vary by store and how much they have in hand.. If they had lot of the same title, then it would be a very low trade in value. If they do not have that title, it would be a higher trade in value, as for what I think. Do not rely on the boards for how much they're worth. Simply, pick up the phone and call both EBGames or Gamestop for their values.
