The centres are $9 each, weigh bugger all but the company selling them wants $200 for shipping to UK???? WTF

Is there anyone in Canada who would be willing to have them shipped to their address and then forward them on to UK at a realistic cost. I dont mind sending payment as a gift via paypal and my neighbour will pay for the goods and initial shipping to your Canadian address
The items probably weigh a couple of oz each and are approx 2" in diameter. Ive tried turning some out of alloy in the lathe but as they need to clip into a ridge in the wheel centre, the alloy tangs snap off due to lack of play/flex. I cant get a good enough finish on the plastic thats available
Can anyone help?
Thanks
Paul
