Amazon often decides to discount the price of books. Amazon lowers the price of books in order to remain more competitive to sell more books—and will sometimes discount it down to $.99/book temporarily. Even if the book is discounted from the original list price, the royalties that the author receives from the book with not be affected. Unfortunately, it is near impossible to control Amazon discounting the price of the book and it can be difficult to change the discounted price they list for the book.
