This is the same here in Spain , every parcel , regardless from UK , we have to pay import duty on.
My daughter sent me a few things from UK for my birthday, total value about £15, but had to pay E37 on collection !!
Also, when buying on Ebay, so many sellers are UK based ......
I'm not prepared to pay, so either end up buying locally or buying from some one in EU .
Sadly, this whole exercise has been an opportunity to rip off the buyer .
