 Last time, one of the top selling books on Amazon was a fake book. A fake, you can't joke about that. That was just a blank book. And it was horrible because more than a thousand of them sold. And it was, that happened before they could get it taken down. And so then people, once it got taken down, went on my real book, Amazon, and rated it one star for the book being blank, which it wasn't. So just make sure you're going to legitimate.
