Prime Big Deals Day Gas Discount: $1 Off Per Gallon (Oct 3 Only)

One day only: Friday, October 3, 2025. Updated with redemption steps, FAQ, and savings tips.

The Prime Big Deals Day gas discount gives Prime members $1 off per gallon at participating stations on October 3, 2025. As Reuters’ business coverage notes, Prime Big Deals Day is Amazon’s flagship fall sale—making this fuel perk a smart, real-world way to cut costs while you shop.

How to Redeem the Prime Big Deals Day Gas Discount

1. Confirm you’re a Prime member. (New? See our Prime Young Adult guide for discounted/free sign-up options.)
2. On Oct 3, open the gas promo on Amazon’s Big Deals Day page and activate it.
3. Drive to a participating station (availability varies by area).
4. At checkout, follow Amazon’s redemption steps (barcode/code or membership verification) to apply $1 off per gallon.

Pro tip: Activate the offer in your app before you pull up to the pump so you’re not fumbling during the fill-up.

Eligibility, Locations & Limits

• Date: Valid only on October 3, 2025.
• Who: Active Amazon Prime members (households can coordinate one fill-up to maximize value).
• Where: Participating stations (shown during activation).
• Discount: Flat $1 off per gallon; gallon caps may apply per transaction—check activation details.

Tips to Maximize Fuel Savings

• Refuel when low. A near-empty tank maximizes the dollar impact.
• Stack card rewards. Many credit cards still award points/cash back on the final charge.
• Verify participation first. Check eligible stations so you don’t waste time or gas.
• Time your errands. Fuel up, then shop Lightning Deals from home for faster checkouts.
• Share the plan. Decide which household driver fills up to make the most of the one-day window.
