I have admitted elsewhere on this board that I am something of a degenerate book-buyer. Sometimes I am actively searching for certain titles or categories or authors, but I've also been in shops and thrift stores where I'll buy the "best" available book for a "fix". Of course, price is a major consideration when one's buying habits become compulsive, but I buy most of my books at flea markets, thrift stores, library shops, and the like. I've bought loads of books for $1 ea. because I was willing to wager $1 that they woiuld turn out to be interesting.
