Gamestop has had some surpirisingly good trade-in deals in the past few weeks. Granted you'll only be able to get one fully priced game or at least two discounted games. I recently got Uncharted 2:GOTY Edition and God of War 3 for 65 bucks. The rerelease of Uncharted 2 only cost me 40 bucks and it comes with avatars, map and expansion packs which totaled about 20-30 bucks if you bought them all separately online. I got lucky with the God of war game.
