This book is only available to customers in the following countries: United States.
The same goes with other e-bookstores too. I am sure that there exists a perfectly standing reason in some legal universe that does not allow me to buy an eBook version of Dune because I live in Greece, while at the same time I can go to Eleftheroudakis, or Politia and buy the english version in paperback!
To make it even funnier, I can buy a Greek translation of Dune from e-bookshop.gr (which is what I did in the end). So if I live in Greece and cannot read the native language, I cannot buy the eBook version!
It seems to me that only O’Reilly, Apress and Manning “get” it about eBooks. The rest seem to try and reproduce their current business model in a new paperless medium. We’ve got news for you: An eBook is not a book. It is now time to understand that the book is the content and you’ve been selling the medium.
