No. But then neither can Amazon, Barnes and Noble, Walden, or Books-a-Million.
The only one that can guarantee your book will sell is YOU, and you can do that by writing an outstanding book, providing a mind-blowing package, and doing a bang-up marketing job. This includes talking about your book on Twitter, Pinterest, Facebook and Twitter (for starters), and by channeling your followers to this site to check out your goods.
In other words, you’ll have a better chance of getting a sale when you let people know that you and your book exist, and you can begin by registering your book with this site.
