To get the most out of a grocery cashback credit card, you really need to be across all the details and fine print. From one card to another there will be variations in the rebate percentage given, and within an individual card there may be different cashback rates for different supermarket chains. As well as this you need to be aware of any monthly, quarterly or annual cap on the amount of cashback you can earn, and whether the cashback percentages are dependent on, or vary with, the amount you spend. Add to this the extra complications of cash gifts you may receive on sign-up or first purchase (as well as, or instead of, an annual fee waiver) and it quickly becomes apparent that not all grocery cards are created equal. However, it’s almost a certainty that there will be one that suits how often you shop for groceries, where you do your spending and how much you spend.
