This article suggests Amazon will be launching a bookstore in Spain in the next month or so. I'm not sure it matters that much to those of us who write in English-- I've sold a big three books in Germany so far. (By way of contrast, I sold around 300 copies in the UK store last month.) It's always nice to see a new market open up, but I don't know how much demand there is for English-language books in Spain. But I could be wrong, and these markets might begin to expand saleswise. Who knows?
