A Kindle Countdown Deal is a special kind of sale that Amazon makes possible for Indie Authors who are anrolled in KDP Select. The author can choose in advance to put a Kindle e-book on sale for a specified period of time. Since Amazon will tell people when the sale ends, this often creates a feeling of urgency in the customer's mind, very like short sales advertised on television and elsewhere. There are other advantages as well. Normally Amazon gives you a lower royalty percentage for books on sale for less than $2.99, but if your regular price is $2.99 or over, they will let you keep your royalty rate the same even if you put it on sale for less. They also maintain a page where e-book bargain hunters can go to find out what is on sale, so your inexpensive book will be promoted to just the right demographic.
