That's a very kind question, thanks! In terms of what I get in the end, it doesn't really matter where you buy it (e.g., Amazon, local bookstore, whatever), although I'd love it if you supported your local bookstore -- they need help! Format matters a bit more in terms of royalty percentage (I get a higher percentage on ebooks)but ebooks also are priced lower, so the net to me between paperback and ebook is not much different.
