Never thought of e-books because I grew up with real books and can not imagine people looking at squiggles on a screen. My bad.No.
85% of my published sales are ebook, and the publisher gets 40% of net from the vendors.
I self-pub as ebook and POD paperbook through Ingram. There are slightly less physical book sales due to the cost of the paperback, but I make more money because I get 100% of the payment from vendors.
Hope Trump can make it work. I might break down and try one myself.
