Query: Why buy a book?

That is a verbatim copy of a website? I purchased the book because I found the website informative but the book is a some-what abbreviated version of the website. One does not need to pay [money] for a poorly-written 90 page book when all the information is available on the website. I don't care how motivational some people think the book is, they should get the same motivation from the website. ALL the information and workouts in the 'book' are available for free on numerous natural websites.I returned mine the same day. The author accuses the industry of being greedy and wanting our money. I find this "book" to be more of the same. Especially when the author has no real credentials. A person that eschues steroids but quotes Swartzeneger?
