Heads up, savvy shoppers! Stop & Shop, Giant, and Martin's are offering a sweet deal: you can earn 3x fuel points when you purchase Mastercard gift cards. This offer is valid from November 21st through November 27th, so act fast! Remember to double-check your local circular to confirm the offer is available in your area.

Why should you care? Well, these fuel points can be redeemed for discounts at Shell gas stations (up to $1.50 off per gallon!) or even on groceries! Every 100 points equals 10¢ off per gallon (up to 20 gallons) or a $1 discount on groceries. Plus, you can use a credit card that earns bonus rewards at grocery stores to maximize your points haul. Consider stacking this deal with a Chase Offer for extra savings. Keep in mind some stores have a daily $2,000 limit on gift card purchases, and might require you to put the whole amount on a single card for the points.

Bottom line: If you're already shopping at these stores and buying gas, this is a great opportunity to stock up on gift cards, earn rewards on rewards, and save money on fuel or groceries. Happy spending (and saving)!
