Nope... think of them as a distributor. So yes, they sell physical copies, but if you have an ISBN they'll get you into the book catalogue and real book stores can order your book. They'll also make a downloadable version of your book that you can sell direct from their web site, or from yours. They'll also (apparently) get it into the iBook store for you. They take a pretty good cut of the money, but for me, it's been well worth it - and I haven't bought any services from them, only paid them commission on my sales.
