It took me too long to find the purchase link. I eventually clicked on the picture of the book and that worked. I was looking for another buy link for too long though (really, only 20 seconds maybe, but that's probably too long).
Thanks for mentioning this. The post was designed with the idea that people would read through the whole thing before deciding to buy (there are two links towards the bottom).
I always get annoyed when I navigate to a page and there are HUGE buttons telling me to spend money. So I tried to not do that.
Although, I may have pushed it too far in the opposite direction.
