Shopping for unusual books at the last minute?

I have blogged about this site before (a long time ago) but it really rocks. I usually forget it's there until I get desperate to find a used book. I just used it to find a book I was having trouble finding locally either used or new. I found a cheap, used copy in a local store, called and they're holding it for me to pick up tomorrow. Just in time to give as a birthday gift. And yes, I seem to always shop at the last minute. When I post about something else later you're likely to find this post ironic. (We call this foreshadowing.)
