I feel like I'm missing out as I hear this being mentioned, but don't understand it
If you're going to buy something on the web, rather than go direct to the retailers web site go to quidco (or one of the others) and click on the quidco link. That sets up a referral cookie so that when the retailer pays the referral fee to quidco, quidco pass most of it on to you.
You register and set up either a paypal account or bank xfr and your money goes in. Amounts available vary - some very good numbers for eg mobile phone contracts and insurance policies, down to the 2p I got the other day for a cheapy ebay purchase.
I know someone mentioned set up with paypal etc. But when you buy can you pay with a different credit card?
Theres also Topcashback, http://www.topcashback.co.uk/ which unlike quidco does'nt charge you for their service, also when using these sites you have to clear your cookies if you've visited a site prior to returning through a cashback site. Alan.
Quidco pay you all the cashback money they receive. They charge £5 a year fee but take it only when you have earned more than that in cashback so there is no bill to pay.
