This is really an experiment to see if it's worth losing the benefits of Amazon Select in order to expand into the EPUB market. If the benefit doesn't outweigh the cost, I may take the book down from the alternate sites and stick with Amazon. Alternatively, because Select membership is a 90 day contract, I might go 90 days on Amazon Select, then 30 days off, and so forth.
One of the greatest benefits of publishing on your own is that you can always experiment in any number of ways, in order to find the strategy that works best for you and your readers.
