I got an answer from
Sandman Slim's author Richard Kadrey about the availability of his novels outside the USA. He (or his publisher) is showing around
Sandman Slim in other countries, he doesn't know the status but hopes it will soon be available in the Netherlands.
He actually advised me that if I wanted to get his novel I could look on BitTorrent

. I have a lot of books on my TBR list at the moment but when I'm done with those I think I might opt for the BooksOnBoard giftcertificate and fake US address trick so he gets his money.
