eBook Price changes:
Amazon suggests you price your book between $2.99 and $9.99. If your book is priced within this range and purchased within their territories, you will receive 70% of those sales. If the book is priced below $2.99 or above $9.99, they will only pay 35% of those sales.
The price you chose must end in .99 and will be the same price that is delivered to all retailers. The minimum price we can deliver a book to Amazon and Kobo is $0.99, and Gardners has a minimum price of $1.99. If you select a price lower than what can be delivered, then your book would need to be removed from distribution at those locations
