Even if you don’t receive physical cash, you can use rewards towards purchases. For example, you can use a Visa gift card or gift card to a grocery store, like Kroger, to buy groceries or other supplies. If the grocery store has a rewards program, you will gain point that can be put towards future purchases. Some gas stations and grocery stores with gas stations have rewards cards. Use your gift card when buying gas. You can then use your rewards points to buy gas in the future. First, you will need to complete the free sign up for the rewards program at your local drugstore/pharmacy. Then, use your gift card from that store or Visa gift card to make purchases. For each purchase you make, you will receive points. The points can be redeemed for discounts or coupons. If you have an unused gift card that you don’t want, give it to a friend who would appreciate it. For example, if you have card to a coffee shop but don’t like coffee, gift it to a friend who is a coffee lover. Make sure that the card hasn’t been used if you are giving it as a gift. If some of the balance has been used, you can tell the friend in advance and ask them if they’d like to use the rest of it. If you will not be using your gift card, a very generous thing to do is donate it to charity. Even if you used some of the balance, you can donate the remaining amount. A couple websites you can choose to donate your card to are GiftCard4Change and Charity Choice. Typically, you will receive a receipt for your donation that you can use as a tax write off.
