I hate dixons and stuff like that, partly cos most of the stuff there is rubbish and expensive, and you cant buy ANYTHING (well, maybe a pack of bateries) without them going on for hours about insurance, accesories, waranties and dont listen when you tell them you dont want anything else
I heard of somthing though if anybody wants to try, ask the assistant if the product is reliable and will last more than about 3 years. They will probably reasuure you that of course it will. You can remind them of this when they try to sell you the extended waranty. Then watch them back track and talk s**t!!
