Grocery fuel points
Supermarket programs convert grocery spend into cents-off at partner pumps — the strongest mainstream fuel discount.
Warehouse club pumps
Club gas routinely undercuts nearby stations enough to justify membership for two-car households.
Price apps before the drive
Station-price apps show the spread on your route; crossing the street is sometimes 20 cents.
Brand apps for the loyal
Chain fuel apps knock 3-10 cents off per gallon and stack with their gift cards bought discounted.
