Authors who have their books available to purchase direct from them would love your support in that area. We're always thrilled with ANY purchase, pages reads, etc., but buying direct from us allows us a bit more in royalties, and it makes us not AS reliant on the big book platforms.
ALL of my paperbacks are available from my direct store (https://payhip.com/ADEllisAuthor) and a large chunk of my ebooks (the ones not in KU) are also available here.
