Understand where you can use it to get cashback
As you can see in the example above, different types of purchases sometimes attract different rates of cashback.
Some cards are issued by supermarkets or other commercial organisations, and will pay a higher percentage on purchases with them and a lower percentage when used elsewhere
Is there an annual fee?
A number of cards offering cashback also charge an annual fee. These fees can range from £25 to over £40 a year. If you’re earning 1% cash back that means you’d need to spend between £2,500 and £4,000 a year on the card just to cover the cost of your fee
