> I have sold just over 500 copies, for gross revenue of $70,714.20 Er... what? Each copy of the book is $140?!?

  That's what it sounds like. You have to realize, that anyone that actually has a performance problem is likely to save many multiples of that monthly. Just getting an engineer to look at a performance problem for an hour is costing a company at least $100 (probably more in opportunity costs). If you can save time with some training it's totally worth it to buy a book like this and give it to one of your devs to see if they can reduce your AWS footprint. Mostly likely most of that $70k came from corporate credit cards.

  The book is part of a bundle of course materials--so it isn't exactly all of that money for the book alone. The book may represent a significant part of the value, but it's a bit misleading.
