The Gamefly used game store has lowered the prices on some games and added a few new ones. Below are the better ones I noticed.

Shipping is $3, and prices listed are before shipping and tax.
A few games have free shipping, and all GameFly members receive free shipping on any game.

Note: You can only purchase one game at a time.

All titles include case and manual (in mint condition) and are guaranteed; however, this company is primarily a game rental service, and the quality of each disc will vary.
Many people receive games in great condition, while others have received their games in poor condition. I have purchased 3 games from them so far (all PS3) and each one looked great.

* A quick note about Alone in the Dark: AFAIK, there is no confirmation of a patch to include the PS3 fixes for the 360 version. Some people might like the game the way it is, but for anyone who wants to buy and wait for a patch, it might be better to hold off for now. Source: Two Joystiq articles. (10/10), (9/12)
