The UK retailer Dixons/Currys has a rather mixed reputation. Some say the sales staff aren’t as well-trained as they might be, or that they push extra warrantees for the commission, and there are stories of poor after-sales service all over the web.
But, but, but. I’ve just bought a Nikon D80 from their website with no trouble at all. It was very competitively priced and delivered on time. So, tentatively, thumbs up for Dixons. I’d buy from them again.
