Re: I got mail from German Customs, do I have to pay?
In some countries books are duty free. Ask if that is the case for your country. We do mark the shipments as a gift and value @ $24. The shipping order (not enclosed with the shipment) shows retail price and a 100% discount. I can send that over as a PDF if the helps.
If you need to justify the value, it was a gift from the publisher and that was the cost of printing.
