Raise your price to $2.99 on your official launch day, and leave it there for about three days. At $2.99, you get the 70 percent royalty rate from Amazon, so you’re making around $2.10 per book (versus $0.35 at the $0.99 price point). For days four through six, keep an eye on your Amazon rank and sales. If sales are strong, you can either ride the wave of a lower-priced book for an even higher ranking, or you can slowly raise the price by a dollar every day or so.
