GameTZ.com is a huge trading/buying/selling website for games (you could get some books, movies, and cd’s there too) but thats where I bought most of my old games that you can’t find anymore. the only thing is, you have to subscribe and pay to use the website. for me, it was well worth it. You can still search for games on it if you are not subscribed. also, theres another website.. i dont think you have to pay for it but its called TGN (trade games now) i think the website is tradegamesnow.com Good luck!
