We know this seems unusual these days. However, we are only a small group of people doing all the work in our free time. Thus, we cannot afford a dunning or loose time with unpayed orders. As we had to learn from experience, orders paid in advance are fetched at the post office or accepted at the door more reliably. Besides, the customers will care more to use a correct address, so we can avoid additional costs for undelivered or refused items which happened sometimes in the past. Thanks for your understanding.
