Sorry for going off the topic a little, but the Irish post office have more than doubled their price for sending packages to Europe and the U.K. It went from about 17 euro to 27 euro in one day.
Also, DHL can send up to 5 kg parcels to Ireland from Germany for about 19 euro, while they charge over 70 euro for the same package going the other way!
I think it might be cheaper to send parcels from the U.K. to Ireland than it is from the U.K. to Europe, but it usually costs me about £12. I think when I got stuff from Ardbeg, it was only £8.
