It is a bit evil! Baen also bundles ebook cds with their hardcovers -- I got the entire Vorkosigan series (save one that apparently hasn't been published as an ebook) when I picked up the hardcover of Cryoburn. ♥

Munseys! Yes, that site has an interesting assortment -- picked up some terrible pulp novel from them. (I sometimes read horrible books on purpose. I can't begin to explain it.)
