Cash Back Sites?

Just wondering if anyone uses anything like this? And would you recommend it?

I use Quidco.com - just google it...

Have got over £100 in cashback since January this year, and I don't do a lot of stuff online.

Get cashback mainly for insurances throughout the year, Next, Debenhams, flower delivery and train tickets etc and some gifts and stuff I've bought

I use Qudico.

There's loads though, cahbackkings, fatcheese, quanti, worth looking around to see who pays the highest. Some take annual fees some don't but then don't give you as much cashback.

I use quidco and couldn't recommend it highly enough, made over £200 so far just buying things I would buy anyway. £5 a year subscrition which you only pay if you get cashback, so it comes off your first payment.
Brilliant!
You do get a bit obsessed though, I don't buy anything until I've checked to see if I can get it through quidco first.
