I looked again at the Ebay item - The Zeppelin in combat by Douglas Robinson - and it is still there, no bids at the moment. Just to see what happened, I changed the shipping destination to the USA and lo the shipping got down to
$ 3.16 (remember for Europe - Netherlands it was
$ 33.00). I also tried Bulgaria ( $ 31.00), Canada ($ 22.50).
So the idea of FliegerJG1 to send the book to a friend in the USA who will ship it via the cheapest way to Europe is an interesting option
