Update: I received an email from Rod, at PineGrove Leather, advising me in friendly terms that, since the new EU set-up, it would cost me more to receive if posted by them directly. He offered me the option of cancelling the order, then going through their EU outlet (Etsy...), for which he'd create a special 'one off' sale for me to order. The result is lower postage costs, and no import fee from the French gumment. I've accepted this solution, and the original order has been cancelled, with the new one now gone through. I think this is worth mentioning as being Good Customer Service, for an item which is, let's face it, rather small beans for such a company. Other companies could take a leaf from their book in pro-active consideration of their clients.
Well done, Rod, and thank you. Now I just have to be patient and wait for the post lady to stop by..!
