I dunno if that's true any more. Local dealers were offering the same deal I got out of Quidco; for SkyHD in January I paid £230 upfront and got £130 cashback. Not long after, Currys had SkyHD for £99. But now Sky have vanished totally off quidco -- either they've clamped down on it specifically, or they have cut back on all subsidies. I do know that shopping for the best deal on Sky is very hard.
