I use it. My car insurance quote was £157 from both Prudential and Lloyds TSB (as one underwrites the other). I got £125 cash back with free Green Flag roadside and home so it also saved me £114 on AA membership. So I've effectively paid £32 for a years car insurance and breakdown cover.
Just got £10 back from some stuff I purchased for Christmas. It's great for getting some money back when you've found the best deal. Then you check the cashback deals from providers and see which is best.
The best deals are on Insurance, Health plans, bank accounts, credit cards, phone contracts and utility switches.
I just got my 120 quid back from Lloyds TSB car insurance, it takes a while to come through, but it will be in my bank account just in time for xmas

Also got my broadband for £55 quid and gas/elec for £66, so all in all, its a very good way of making some money from what you buy
