Query: The worst ripoff I have gotten sucked into!

I am so thankful that I bought this book USED at half price, so that I did not further line this charlatan's pockets. What a 100%, UNnatural, ripoff that "he" doesn't want you to know about! This convicted felon of a pseudo-author has done it again: increased his personal wealth through not only misinformation, but NO information regarding cures which he claims on his informercial and in the title of the book. This book is simple and pure: a come-on for you to spend more money on his web site. The book, in spite of his claims, holds no "cure" information on anything. This, by the way, is only my opinion and is not yet sanctified by the FDA (for those of you who have seen the infomercial and/or read the book).
