I think this post can stay here in this thread for now as it now also contains other discussion.
But on the long run the Ads section is a better place for that.

I have one remark about the manual: I would let prospective buyers have a look at it, for example, if it is 10 Chapters, maybe make the first 2 Chapters available. Otherwise, how would anybody know whether it is a good quality book or not. If people are not able to see what is inside, they will either take the risk of buying it or they won't. Or they can try to get information about the book's quality from others.
I case of Dwight's book: he answers so many questions that are related to his books contents, sometimes supplemented with extracts from his book that anyone can easily decide for himself whether it is good value for him or not.
