There is an extremely easy way to make use of Fictionwise.

Set your account to US.
Inadvertently provide a valid US address for your billing address (do a search for a US hotel etc.)
Pay using your normal CC details.
Works 100% for me and you can get the 100% rebates without a problem.

In some rare cases you will get a geographic restriction check before you are able to download the book. In cases like these you will need to use a proxy (Hidemyass works nicely).
Change your password to a temporary password.
Log in using the proxy and your temp password.
Download the book.
Access Fictionwise normally and change your password back.

After the book is downloaded once you will be able to download it again without having to go through the additional steps. No CC info is ever used while accessing via the proxy so there's no risk.
