I've spoken to him about these shipping charges, and he hasn't found away around them yet.
Here's a rash thought; how about looking into producing them in England? Or if no one can match exactly the same product, then have a different UK version/product line. It'll reduce shipping costs for us on this side of the pond and it'll perhaps spur more sales due to the collectibility of the item.
