OK - so if I post to Netherlands then I hope you send me some coins as well ...
I wonder about the exchange rate; today £10 is €12.35 apart from postage. So the other way round then €10 is only £8.10 (postage is £1.47 to Europe so £11.47 is €14.16 today). Sending a €10 note means you are €4.16 better off, apart from postage to UK.
Just thought I would ask.
