What are others?

There was a blue or cloud or something like that in the title website that is really good (maybe something to do with a bright star) but I forget the name

Check GameFly. They're having a year end sale. All games come with original cases and manuals.

Wow. I see some nice deals there.

I was going to mention gamefly too. But no need to limit yourself to used games, you can often get new games cheaper. Gamecrazy is going to have a pretty good in store sale starting on the 28th.

If you have games to trade, Goozex.com has done me right. The only bad thing is a corollary to the good thing (the way it works)--I have a bunch of points right now and no games coming to me, because all the games on my Request list are reasonably new/in demand titles. But I've gotten rid of a bunch of old titles I will never replay and that are worth nothing anywhere else, and I have gotten titles, including new ones,virtually "free" via tradeins.

You can get lucky with amazon.com sometimes too.

I think Gamefly is the best for quality used games online. I've ordered several and never had any issues.
