Cashback Online It’s not a credit card, it’s not a debit card, it’s a CashBack Card. It gives you money back every time you use it at over 40 leading retailers. CashBack earned is on top of any special offers and loyalty points. It works a bit like ‘Pay-as-you-Go’ mobile: top it up and away you go. You can’t get into debt with it and there are no interest charges.
