Where do you guys usually get your games from? Do you usually buy new ones? Do you pay full price, or do you shop around for a deal?

Used to be I'd seldom buy new games. Seems games aren't depreciating in price too quick these days, though. That, or I'm just impatient. I've been looking around for good deals on certain games I really want, but I've been having trouble finding anything that doesn't end up not really being worth the discount (on ebay and such, where you can tell the dealer is still making a profit off their shipping price). Does anyone have any sites that have really good deals on games?
