So who here haggles the sales men in shops?

I've been watchinf Don't Get Done Get Dom. It's a great show, and he deomstrates how eay it is to get massive discounts on goods and how much shops acually rip you off.
I watch it all the time now! It's inspired me. When I get some cash I think I'll be heading in to Dixons or somehwere and getting myself a nice new TV, with a nice discount

You obviously have to be cinfident while doing this, but I'm cheeky so it's all good

Anybody watch the show? Or do a bit of haggling themselves?
