The percentage of cash back you can expect to get from cashback credit cards can vary, although most normally offer 1%, with up to 5% being given with certain purchases.
For each purchase you make using your cashback credit card, you will earn a small amount of cash back.
Using cashback credit cards on a frequent basis can add up to a lot of cash back at the end of the year. This extra cash can really help when it comes to the Xmas shopping.
