An Amazon Secret

I got this the other day, as part of a response to my question about lowering the price of one of my books, Keeping Secrets.  

Amazon.com, as well as other retailers, sets the selling price of items on its website. In some cases, the selling price will be above the list price; in other cases, the selling price will be discounted to a price below the list price. Keep in mind that you set and control the list price of your work, while the selling price and any discounts are set at the discretion of the retailer and are subject to change.

Only you can alter the list price you set in your CreateSpace account. The royalties you earn from Amazon.com retail sales, as well as sales by other retailers, will be based on the list price, not the selling price. Neither you nor CreateSpace has the ability to change the selling price of your work on Amazon.com.
