Smashwords is a good place to sell your books. It gets decent sales – about the same as Kindle – and it also places your books for sale at other eBook sites. So far, I’ve sold my books at B&N and Apple through Smashwords. I just logged into Smashwords and I see that I sold some books back around Christmas at Apple iBookStore. This was before I finished the Harmonica book, so I figure in a few months that I will be seeing some more sales.
