Query: an infomercial in book form

I saw the infomercial on TV so I was expecting information on Natural Cures in the book. The book is also an infomercial, directing you to the Natural Cures Web site. On the Web site you are directed to join for $9.95 per month. Too much money spent and not enough infomation received on Natural Cures (EXCEPT the natural cure for a fat wallet).
