Yes, that is one of the ones I tried. It is faily easy to find out if it is your account or the site. Just log out, and then it shows the correct price. If it changes to "pricing information not availlable" while logged in, that means you are not allowed to buy books. For me if I go to amazon.de it also tells me that and that I should buy from amazon.com. Go to german store and if you see prices for Kindle books, then your account is (still) linked to Germany.
