Just out of curiosity - why do ebooks cost so much? (I am talking in general, not with respect to this particular book). Of course, the value of the content is high etc etc - but wouldn't pricing ebooks less make more people buy them? A $30 ebook is much more expensive, especially if you are not in US/Europe (if you are in Asia, Africa etc), than a $9 ebook, wouldn't the volume make up for the lost dollars? Again, I am not talking about big name publishers, they have their own reasons. I am only talking about independent authors, who have full control over their books/course materials.
