I've been looking around for the best deal on the TV I want (a pany 37px80B) and have been trying to factor in a 5 year guarantee for safety's sake. I understand that john lewis may well price-match, but it was Richer sounds that caught my eye. They're selling the TV for £569 and a 5 year guarantee for 10% of the price. I don't understand how this can be only a 1/4 of the price of the usual 5 year jobs from the likes of Sound and Vision. Any ideas? Or should I just opt for JL and get the manufacturer's guarantee for FREE (supposing price-matching with Richer Sounds)?
