CafePress is launching its self-publishing and selling platform for book authors sometime this week. (It's in beta now here, where it says the launch is July 28...)
The price is higher than it would cost you to print books or reports at a standard print shop (or Kinkos), but that's because it includes all the online sales backend stuff you need too -- such as a Web page to sell from, a shopping cart, shipping services, and customer service.
Might make sense for anyone who wants to test a book or report sale without investing in building all the backend first. If sales go well enough, then you get serious and move to your own systems....
