Does anyone else here use cashback sites and have they successfully paid you for the offers they gave you? How do the companies that offer 100% cashback get their money and not make a loss? I recently took up one of their offers for 100% cashback on purchases upto £15 at CadburysGiftsDirect through Quidco. Yet to receive the cashback at the moment but hopefully I will have it in my Paypal account soon.
