BRL, thanks for the offer, it would appear that we are getting down to the final stage of negotiations where your help won't be needed.
419, I did wonder about VAT. When I was in England in 1992 I bought a stereo receiver which I wouldn't have bothered buying except for the promise that I would get a refund of the VAT. 11 years later I'm still waiting; a nice little earner for the British government and one wiser aussie
With a total purchase price of about 150GBP (and I don't know what the VAT percentage is) it's hardly worth the bother, but as you say, better in Binoette's pocket than theirs.
Thanks again to everybody for your help.
