Ah, don't misunderstand me about going to used book stores (and yes, I am a book-hoarder, too) -- it's just that at the used book store I like to let random books find me rather than going there to look for specific books. When it comes to specific books I get them at the library (which also is super-convenient for me since I'm a librarian at a public library and therefore I am at the library five days a week.
