Their regional restrictions have been tightened up recently also. I have over $15 in micropay rebates to use, and wanted to buy a book but it is only available in the US and Canada. In the past, I just set my country to US when I needed to. Now when I do that I get an error saying my order location does not match my account info. I guess they can detect I'm not in US.
These region restrictions are as insidious and evil as DVD or BluRay regions, and should be outmanoeuvred whenever possible. I haven't yet figured out as workaround for this latest restriction system but I will certainly be avoiding Fictionwise for all future sales as a protest, unless I absolutely have no other option...
