nk497 writes "Retailer Kogan is offering customers of rival stores free HDMI cables to highlight the 'scam' of selling the cables for £100, saying its own £4 cable works just as well. 'An HDMI cable is an HDMI cable,' Kogan said. 'It's a digital cable. You either get a picture or you don't. Don't get conned into buying a 'fancy' HDMI cable because it will make no difference!' Rival retailers Currys and John Lewis said they preferred to offer customers a 'variety' of cables. 'Each of our HDMI cables offers excellent quality and value for money, and by providing our customers with a range of different cables which offer different specifications, we are able to help them find one to suit their specific needs, with features such as different cable lengths, ultra slim and high speed,' said a spokesman for John Lewis, which sells cables for £20 to £99."
