I am not able to buy books for my newly bought Kindle. I set up location as Switzerland, language as English and my Amazon acount was created when i was leaving in Germany. Now the main menu is in English but when i go to the store all start to be in german, both the books offered and the menu itself. I do not speak any German. How can i choose the language of the books and the menu when shoping? Also can i actually have books on more than one language to choose from? Thanks a lot for advice
