Where is a good place to buy a chinchilla in the Costa Mesa CA area?

Please, I can't find any place where they're any cheaper than $100, and even though many of you think that at that price all you'd have to do is whip out a credit card and buy it. But anyway, you can say i'm cheap and stuff, but I need a place that sells them almost dirt cheap, or under $90 is good, free is better though ;)
