30 cents per gallon

When I first joined Costco 20 years ago, I was skeptical about recouping my membership fee through savings. But my attitude changed the first time I filled up my car and realized how much cheaper Costco's gas is. Costco typically charges about 30 cents per gallon less than other stations.

Details

This fuel savings alone can cover the annual membership fee, especially for regular drivers. But Costco has a secret weapon stronger than low gas prices: its membership-based business model that drives customer loyalty.

Context

Costco doesn't make much profit from selling gas or other products; it relies on membership fees. This model allows it to offer extremely low prices on gas and goods, creating a positive cycle: more members → more savings → more loyalty.

What This Means for Investors

Costco (COST) has a strong competitive advantage through its membership model, which enhances customer retention and provides stable cash flow. This makes it an attractive defensive investment in the consumer staples sector.

Frequently Asked Questions

Costco members save about 30 cents per gallon compared to other gas stations.
