I spent a little time this evening uploading Scary Night Music to Smashwords. I decided to add them to the distribution channels because they add some value to the distribution chain. Amazon only converts your book to the .mobi format which is what their Kindle reader uses. Smashwords takes it a few steps further and converts to .mobi as well as the required formats for the iPad, the Sony reader and the Nook, as well as most other eReaders on the market today. They also distribute the eBook to Apple iBooks, Amazon, and Barnes&Noble. So i seemed like a good option since it was free and they even furnished an ISBN at no charge.
It required a little digital manipulation of the file formatting, but it wasn't too time consuming. If you'd like to take a look at the page they furnish, HERE it is. If you'd like to add Smashwords to your potential distribution list for eBooks, it's relatively painless. If you have any questions I can help with, let me know.
