International shiping agreements between mail companies allows goods to be sent at sender's rate - I have ordered goods on eBay from Hong Kong or China - they have arrived within 2 weeks - cost of item + postage is less than just the postage in the UK...
It's a crazy world we now live in - just wait until the Chinese economy matches that of the USA or Europe, and we have to pay the 'real' costs... We'll have lost all our own manufacturing and be totally dependent on imports.... Then they'll charge what they want....
Meanwhile we can enjoy cheap goods and even cheaper postage rates...
