This is a bait and switch operation. They set you up to make it appear that you're getting a hard copy book. They take your address, they state "Free Shipping" and they have a scroll down menu that says "paperback" version. Then after you pay for the item it immediately arrives in your email as an e-book. I'm not sure if it can be downloaded as I didn't open the document. There is no live person to discuss the scam with. They will correspond via email and they will not issue a return. In addition, when you show them proof that you've been scammed, they quit answering your emails. I found other people, online who have had the same scam pulled on them, from this company.
