Comet have a clearance auction site for their returned/damaged/ex-display stuff. I bought a fridge freezer from there a few years ago. It had a small dent in the side panel but as it was going in the garage anyway, I thought the price was worth it.
When it comes to TVs it's a different story and some go for almost full retail and with delivery on top. I took a quick look this morning, just in case there was a bargain ready to be snatched but no. Instead a 500 quid Sony going for One Thousand Pounds
