Are you upset about this?
There is quite a furor going on at Amazon about the pricing of Ken Follett's book, FALL OF GIANTS on Kindle. It is $ 19.99 for the Kindle and LESS for the hardcover. It is being trashed by reviewers for this reason. No one wants to pay more than $ 9.99 for an ebook. I agree.
My question, is the iPad crowd annoyed by this too? It is $ 19.99 I believe in the iBook store.

I have found the best way to protest high price is to not purchase it. The seller will quickly get the message. If you just hollar about the price and still buy it then the seller know's your not serious.
