Why Costco is winning the gas war by refusing to behave like a normal gas station
With the conflict in Iran pushing gas prices higher , Costco ’s fuel program has quietly become one of the most effective ways for consumers to cut expenses. Even as national averages climb, Costco’s gas is typically $0.05 to $0.40 per gallon cheaper than local competitors’, savings that can be crucially efficient during a price surge. Costco’s edge comes from its membership model. A $65 Gold Star or Business membership, or the $130 Executive membership, unlocks access not only to the warehouse’s discounted goods but also to its lower fuel prices. “I got gas at Costco for $2.99 and it’s $3.60 everywhere else. Wild it’s so much cheaper at Costco,” one user wrote on X . Costco operates roughly 550 gas stations across the U.S., giving members plenty of opportunities to take advantage. Gas isn’t a small line item for the retailer, either. Costco reports that fuel accounts for about 10 percent of total net sales, a steady revenue stream that helps the company keep prices lower.

As gas prices surge due to geopolitical tensions and instability in oil markets, Costco has emerged as a surprising winner in the "gas war" by refusing to play by the traditional rules of the game. With the conflict in Iran pushing fuel costs higher, Costco's fuel program has quietly become one of the most effective ways for consumers to cut expenses. Even as national averages climb, Costco's gas is typically $0.05 to $0.40 per gallon cheaper than local competitors, offering savings that can be crucially efficient during a price surge.
Costco's edge comes from its unique membership model. A $65 Gold Star or Business membership, or the $130 Executive membership, unlocks access not only to the warehouse's discounted goods but also to its lower fuel prices. "I got gas at Costco for $2.99 and it's $3.60 everywhere else. Wild it's so much cheaper at Costco," one user wrote on X. This model provides Costco with a steady stream of revenue, as gas accounts for about 10 percent of total net sales.
Operating roughly 550 gas stations across the U.S., Costco gives members ample opportunities to take advantage of its competitive pricing. When gas prices soar, Costco often drops its margins and lowers pump prices by $0.30 to $0.40 per gallon. Even when the market settles, Costco still undercuts competitors, typically by $0.05 to $0.15 per gallon.
As of March 16, the national average gas price sits around $3.70 per gallon, according to AAA, a price that's been inching upward for weeks. Across the U.S., gas costs are significantly higher than in previous years, driven in part by Israeli attacks on Iran and broader instability in oil markets. President Trump has offered limited commentary on the issue. Earlier this month, he told Reuters he has no concern about rising oil prices and expects costs to fall once geopolitical tensions ease. "If they rise, they rise," he said.
With prices pushing toward $4 per gallon, the U.S. is nearing the highs last seen in late 2023. AAA warns costs may continue to climb as winter turns to spring and more drivers return to the road. Costco's fuel program, however, remains a beacon of relief for price-sensitive consumers, leveraging its membership model and economies of scale to offer competitive pricing in an increasingly volatile market. For many, Costco's gas stations have become not just a place to refuel, but a strategic choice to save money in the face of soaring fuel costs.
