Worth noting that the $80 ($100 after initial intro discount expires), was a direct response to strong backlash after they published the original pricing two days back of $150 ($250).

Twitter (where Steven and Adam are active) was fierce with debate per the merits of the price[1]. The $80 "basics" package was introduced in an immediate response.

bought it earlier, read it pretty quickly. It's good, there is some gold in there and a lot of practical advice. It does feel a little bit expensive though, some sections are a little thin and this is made worse by the use of multiple blank pages between sections which makes it feel like the authors have padded it out.

On the other hand I'm likely to refer back to this book a lot over the next few years, so in that light $80 doesn't feel that bad.

I think I'd have preferred a living resource / subscription model rather than a one off book though.

I agree, that price seems too much without knowing how much I will like it ($79 and $149 USD). I'd suggest they break it up into 2-3 books at a lower price so it doesn't feel like such a commitment :) It does look very good though!
