Can I just drop a word of love and appreciation for Abe Books? I don't buy physical books a lot, but when I do, Abe is definitely the first place I look. The books drop ship from the actual seller, and it's remarkable that I've never had a problematic delivery, after a dozen or so.

My favorite book I've gotten from them was A Psalm for the Wild-Built, which was previously a library book, funny enough.
