That's what I like about Lulu. "Adventures With Mistress Zara and Mistress Kassandra" has only sold 12 copies, but it cost me nothing to upload the file there and I get the royalties for the 12 copies paid quartterly. 😀 😛
(Not going to retire on them, $5 royalty for an ebook sale, $3.78 for a hard copy sale.)
