Wow - $97!
I am in the process of writing a comprehensive travel guide myself - but would never dream of charging more than $20 for it - tops.
It makes me wonder what it is - I already have a method of earning 10K miles/month for free - his method has a cost associated with it.
I also have some other methods that generate miles at about the cost levels he is talking about - but they aren't completely straightforward - would only work where certain banks have ATMs readily available.
And I wonder if he will really shut his website down after selling 500 copies - I bet he will just keep on selling it. It looks to me like he is an experiences online resaler with lots of advertising costs bringing people to his site - some of whom will pay his rip off rates....
