You realize Lulu(which Tom used for the ebook) offers pretty much the same service? On-demand prints of books.
Both of these still have a bit of cost involved since you need to order a test copy of the book for approval etc. Also time issues since you need to rework the layout from the ebook version a bit and other stuff like that.
I'm aware. At least as of the time that we were doing our print runs, CreateSpace was leaps and bounds more profitable for us. It seems they've upped their own base cost per book, so maybe they're more even now. CS does offer automatic Amazon listing. Not sure about lulu.
