Warehouse clubs like Costco and Sam’s Club are well-known for offering some of the cheapest fuel prices around. But while the savings are real, there are a few things drivers should know before relying exclusively on warehouse gas stations for every fill-up. Here’s how to maximize your savings—and avoid common pitfalls.
- Membership is Required
To access gas pumps at Costco or Sam’s Club, you must have an active membership.
- Costco: Memberships start at around $60 per year.
- Sam’s Club: Memberships typically start at about $50 per year.
Factor in the membership cost when calculating your potential fuel savings.
- Prices Are Consistently Lower
Warehouse stations are famous for undercutting local competitors—sometimes by as much as 15–30 cents per gallon. Over time, this difference can easily pay for the cost of membership if you fill up regularly. - Be Prepared for Longer Lines
Cheaper gas attracts crowds, especially on weekends and during peak commute hours. Some locations can have wait times of 15–30 minutes or more. Try to fuel early in the morning, late at night, or during midweek to avoid the rush. - Quality Standards Are High
Costco, in particular, is certified as Top Tier Gasoline, meaning it contains detergent additives that help keep engines cleaner and running more efficiently. Sam’s Club gas also meets or exceeds industry standards, but it’s a good idea to check your local club for specific certifications. - Limited Payment Options
Costco gas stations only accept Visa credit cards, Costco Shop Cards, or debit cards. Sam’s Club stations are a bit more flexible, accepting a wider range of cards, including Mastercard and Discover. Always double-check your payment method before heading to the pump. - Fewer Add-ons at the Pump
Warehouse gas stations typically focus on efficiency, offering pay-at-the-pump service without additional amenities like air pumps, car washes, or full-service stores. Plan accordingly if you need these services elsewhere. - Best Savings Come From Combining Membership Perks
Both Costco and Sam’s Club offer additional fuel savings if you use their branded credit cards:
- Costco Anywhere Visa Card by Citi: 4% cashback on eligible gas purchases (up to $7,000 per year).
- Sam’s Club Mastercard: 5% cashback on gas purchases (up to $6,000 annually).
Should You Rely Solely on Warehouse Stations?
Warehouse clubs offer excellent savings, but it might not always be convenient—especially if you have to drive out of your way or wait in long lines. It’s smart to have backup options using apps like GasBuddy for times when warehouse stations are too crowded or less accessible.
