CentsOff Marathon, powered by Drop Tank
Drop Tank was created to expand the market for fuel discount rewards. Drop Tank’s fuel discount rewards can be used for gifts, promotions, and incentives at thousands of gas stations across the country. Drop Tank’s CentsOff Marathon rewards are redeemable only at participating Marathon locations.
To reap those benefits, you simply need to swipe your CentsOff card at the pump or enter the CentsOff code prior to paying for the gas. From there, you can pay and fill up as you normally would. View the company's how-to videos to learn more.
