So after 65 replies, are HDEW a reputable company who pay all neccesary taxes, duties & VAT etc., and if I do decide to buy from them am I perfectly legal. They do say that they offer a three year guarantee.
Although fortunately I didn't need Nikon's extended guarantee on my D90 and the coolpix model bought for my granddaughter, I had a whole lot of trouble getting Homeserve ( I think that is the name of the company Nikon use for repairs) to acknowledge my purchases in writing, but perhaps had I had a problem it would have been sorted, although its a bit worrying when you can't get anything in writing.
