I've just started trading on Goozex and it's great. Goozex is a game-trading facilitator. You rifle through your stash of old games and decide what you want to get rid of. You list each on Goozex and the system will match you up with someone else that wants the game. Then, you ship the person the game; and, once the "buyer" confrims receipt (with positive feedback), you get a certain number of points added to your account. You can then "spend" those points to get games from other traders. The only cost to you is: $1 paid to Goozex for each "buy" you make (you purchase "trade credits" through PayPal and spend those credits to get games, you don't use the trade credits to sell games) and the shipping cost of sending out the games you're getting rid of. You can also buy points if you're lacking in games to give away. I got rid of two games pretty quickly and am in line waiting for two new games (Madden 09 and NCAA 09 for Wii). You get much better value for your old games (and can trade more types of games) than selling them to Gamestop. If you're the type that routinely gets rid of old games, give Goozex a try.
