Although Mr. Sugarman can be funny at times in his writing his blatant self marketing overshadows the humor. Also as a sales person who has done a lot of marketing, I can say that marketers are not sales people. In fact this book encourages the mistakes made by many young companies of buying into a marketer's hype and believing that they can increase sales. This is only true on simple products like sunglasses. If you sell high tech or solutions pass on this book. It is all about how to trick the customer which is not how deals are closed.
