Ah, got you. I totally understand where you are coming from. It is the reason I went wide for the ebook, which is available on all stores. For printing, unfortunately, amazon was the only feasible choice. I am looking into other options as well and if I find one, I have bookmarked your toot now and will let you know.
The sad things is that indeed, the sales I make on amazon are unmatched by other platforms so far. As a queer person, this sucks big time. As an Indie author who hopes at one point getting enough sales to cover the cost of the cover and editor, I don't think I can ever NOT offer it on amazon.
