Lulu is the oldest of self-publishing sites that I still use, and they
are still one of my favorites.
On Lulu, you can publish both e-books and book in print at a reasonable price. Once you are self-published on Lulu, you may opt in to have your books distributed at several of the big ebook reader sites... Apple IBookstore, Barnes & Noble Nook bookstore, and the Lulu Marketplace. Print books are distributed to Amazon.
The best thing about Lulu is that you keep a whopping 90% of your profits from self-published ebooks!
