There's very good thrift shopping here in L.A.. There's a chain of thrifts here called "Out of the Closet" they benefit aids charities. They usually have some good stuff. I once found a very old English version of the Koran from 1916,
and a first edition
Charlie and The Chocolate Factory. Good Stuff....

i shop at out of the closet too!! i hit up about three different ones... i have my theory about the chain... they typically have really good stuff... but charge a bit much...
