Ok, when I've got advertising by Matt Bacak for Bill Glazer's "Outrageous Advertising" book it looked like a genuine deal. The price ($19.95) was reasonable, table of content and first pages looked very interesting, bonuses from a bunch of gurus did not looked bad either, even though no specifics were mentioned what they are, what else...
Then I checked a few other things. The book is already available on Amazon for $13.57. It's published in May 2009 (right now it's mid-August).
