So you can no longer purchase additional titles in Audible, obly additional credits. So if a book normally sells for $5 you are stuck using a full credit to buy the book. Who gets that extra money? The authors? My guess is probably not. Also you can no longer participate in sales. I'm not happy with this change at all. I should be able to make in app purchases like any other app. This change really, really downgrades Audible and pushes the app back years in development. Bad move Audible/Google
