I bought today at the comic shop: Critical Citadel, which has some sick funny stories in it. Some of it made me think of a gentler Mike Diana; don't click that link unless you're ready for a gross-out. (If you want a picture-free story about Diana you can check the wikipedia article.)
At Half Price Books I picked up an old copy of Piers Anthony's second Xanth novel, The Source of Magic. I recently read the 4th and 3rd Xanth novels (in that order) so I figured I might as well work my way on back to the first. Besides, it was only $1.22, which I paid for with pocket change.
