Admin Heads up, deal hunters: OnePay is giving $1 cash back per gallon of gas every Wednesday through January 15, 2027. Pay for your fill-up with a OnePay debit card or Builder Card using the OnePay Reward gas offer in the app, and the bonus lands on top of whatever cash back the app’s gas offer already pays.
How it works: buy gas on a Wednesday (12:00 AM – 11:59 PM Pacific) during the bonus term of 10/07/2026 – 01/15/2027, pay with an eligible OnePay debit or Builder Card, and make sure the OnePay Reward gas offer is active in the app first. The $1-per-gallon bonus stacks on top of the app’s stated gas-offer cash back. Limits: up to 50 gallons per Wednesday, two redemptions per day.
Who’s it for? Anyone already using OnePay’s debit or Builder Card — and if you’re not, the debit card is free to add and you just preload funds. Wednesday fill-ups are an easy habit to build when each one earns you an extra dollar per gallon through mid-January.
No promo code needed — just activate the Reward gas offer in the OnePay app and pay with your OnePay debit or Builder Card at the pump on Wednesdays.
