I have been selling books for the last decade and started seeing an influx of counterfeit books on Amazon about two years ago. I've even gotten cease and desist letters from lawyers representing the top publishers because I resold a few by mistake. The worst part is that there is no clear way to tell if a book is counterfeit, the publishers wont actually tell you specifics, and the only way to know for sure is to send the book to the publisher. When you send it to the publisher, you will get an answer in about 6 months (yes/no) and the answer is always yes. You have no way to get your original money back for the counterfeit and nothing is learned about how to more easily detect counterfeits. I feel like this is intentionally vague so they can go after anyone for counterfeits and there is really no way to know if you have a counterfeit or not without a lengthy court case. I finally had to get an attorney involved and I just had to pass along Amazon seller information. They went away and I haven't had any issues since then (about 2 years ago).
