One of the most of useful books I've read in the past few years - and that's coming from someone who devours business and marketing related books like his life (business) depends on it.
The book's structure is perfect: 19 costumer acquisition channels, each with a general overview, actionable tips, stories to back them up and help to put the whole thing into context.
Short and to the point, perfectly right and easy to digest content wise.
Highly recommended - especially at the price it's being sold for!
