I run into some bad luck with a few orders I made from amazon. Since May I was not able to get them. The orders were re-ordered since after the arrival time was long overdue, and still did not arrive yet (which is yet again long overdue).
Amazon did not give me any trouble and refund the money in full. I'm very happy with that.
Now I need to think where from to order the books or perhaps to give Amazon another try, but use a "door-to-door" delivery using DHL/UPS to increase chances that my books don't get lost in the way.
