The notion of getting paid to shop sounds too good to be true, but as the credit crunch bites more and more people are registering with websites that offer cash back as you buy.

Shoppers who are really savvy about getting cash back on their purchases may want to consider a cashback credit card too, as these give you a percentage of every pound you spend.

The amount of cash can vary and may be a percentage of your total purchase or a flat fee; most will pay out by PayPal, the online cash system, or bank transfer.
