I encourage Gamestop myself, because they have a 7 day return policy on used games. It's basically a free rental system and has worked wonders with short single player games like God of War 2, which I finished within four days and returned back to GS for a full refund. It's also great for games you are unsure about as far as quality concerns. If you decide you don't like it, you have your week to give it back. Ebay is a great place for game buying and selling also though. I would also add craigslist on that to an extent, but it's not as safe.
