I have bought and sold many items from Ebay over the years and encountered seller who will not ship internationally, for reasons I have never understood, on many occasions the items value is 50% of the shipping cost so guess why I would not even send it back, a sellers dream you'd think !

Thought you may like to know of the following site which appears to allow you as the receipent to organise a pick up in the UK, obviously liason with the seller is necessary but it seems simple enough.
