You realize that EB gives credit on a game by game basis right? For example, when I traded in Mario Sunshine, I got myself $30 for it from EB. That promotion of 2 games plus 20 bucks is a bit hokey because more than likely, they were referring to two old as hell games that now go for 19.99 or less. As far as I know, both games you traded in are still going for well over that amount in retail stores such as EB.
Your gf had nothing to do with it, you just didn\'t know anything about the value of what you were trading in.
