I made a page where I sell my ebook just to sell my ebook. Check my blog PR and other of my sites :)
http://www.minimotherboard.com/ is PR 1
http://www.madhostreviewer.com/ is PR 2
http://tweetrandomizer.com/ is PR 4
It looks like PR 4 is the odd one out and not the norm
I checked the PR of both your blog and the ebook page and it was below 4.
And you are flipping the PR 1 and PR 2 sites. As said in your ebook page copy, higher PR means more money when flipping. Why wouldn't you invest the few hours to make it into PR 4.
I'm sorry to say but your attitude is defensive and a turn off. To my comment and the other comments talking about design of the page, you come across as defensive.
Anyway good luck!
My sites (all appspot apps) do appear to be indexed by google, and usually show up on the 1st or 2nd page of Google results (even after clearing my Google web history).
Thanks!
edit: to answer my own question: install the google toolbar.
