This mainly applies to more recent games but I read that battlefield 3 traded in for 40 and Mario Galaxy for 39 bucks. Figured some people might want to trade games in with this promotion. Was gonna post it earlier but forgot.
I traded in two textbooks about two weeks ago to Amazon and and bought Berlin Alexanderplatz, Eric Rohmer Six Moral Tales, and Umberto D. all on dvd. Total retail price $255. Spent $120 worth of credit.
