You can use a Costco Shop Card to buy gas without a membership-but it's not a true loophole because non-members can't purchase the card themselves
The Shop Card loophole Costco gas method works because Costco's policy explicitly allows non-members to purchase fuel when paying with a Costco Shop Card (gift card), bypassing the membership scan requirement at the pump. However, this is risky move territory because only Costco members can buy Shop Cards, meaning non-members must obtain them from third parties-often at a markup or through dubious channels. The pump will only dispense gas up to the card's balance; any amount beyond that requires a membership to complete the transaction.
How the Shop Card Gas Method Actually Works
Costco's official policy states that membership isn't required when paying with a Shop Card at the gas station. The payment process differs from regular purchases: instead of scanning a membership card first, you simply swipe the Shop Card at the pump. This works because the Shop Card functions as a prepaid instrument that temporarily bypasses the membership verification step.
According to a verified Costco employee posting on Reddit in October 2023, "You do not need a membership to purchase gas with the shop cards. Just simply swipe the card instead of your membership, and you can use the funds on the card to purchase". The same source confirms that gas station attendants have a workaround card for temporary access when payment is made with a Shop Card.
Step-by-step process for using a Shop Card at Costco gas
- Obtain a Costco Shop Card with sufficient balance (must be purchased by a member or received as a gift)
- Drive to any Costco gas station-no membership scan required at the pump when using Shop Card
- Swipe the Shop Card at the pump instead of attempting to enter a membership number
- Pump gas up to the exact balance amount on the card; the pump will automatically stop at that limit
- If you need more gas than the card balance, you must have a membership to pay the difference-otherwise the transaction fails
- Cash payments are not accepted at Costco gas pumps regardless of membership status
The Critical Limitations and Hidden Risks
Despite appearing clever, this method has significant practical limitations that many viral videos omit. The most critical issue is acquisition: non-members cannot legally purchase Shop Cards directly from Costco online or in-store. This forces them to rely on secondary markets where Shop Cards often sell at a 5-15% premium, completely negating Costco's典型 gas savings of $0.15-$0.30 per gallon compared to Station prices.
| Factor | Member Paying Normally | Non-Member Using Shop Card |
|---|---|---|
| Gas price per gallon | $3.45 (Costco average) | $3.45 (identical) |
| Shop Card premium | $0 | $0.17-$0.52/gallon equivalent |
| Cashback rewards | 5% on Citi Costco card | 0% (no rewards) |
| Access reliability | 100% | ~85% (pump failures reported) |
| Termination risk | None | Moderate (membership revoked if caught sharing) |
The 5% cashback reward that Costco raised on January 18, 2026, for users of its branded credit card applies only to members-not Shop Card users. This means non-members using Shop Cards miss out on an additional 5 cents per gallon in rewards on top of the premium they paid for the card itself.
Why Some Sources Claim It Doesn't Work at All
Confusion exists because certain locations reject Shop Cards at pumps. A August 2024 GB Times article incorrectly stated "you cannot use your Costco shop card to purchase gas at the pump" because "the payment process for gas is separate from in-store purchases". However, this contradicts both employee confirmation and real-world testing showing the method works at most warehouses.
The discrepancy likely stems from regional policy variations. Some warehouses, particularly in high-fraud areas, may have updated their point-of-sale systems to require membership verification regardless of payment method. The method works most reliably at suburban locations with lower traffic volumes compared to urban warehouses in major metropolitan areas.
The Real Scam: Membership Card Sharing, Not Shop Cards
The far more dangerous "loophole" circulating involves strangers asking you to scan your membership for them. Scammers claim they "forgot" their card, then use stolen credit cards to pay for gas after you scan. This creates severe legal and financial exposure for you.
"Stolen credit cards get reported, and now you're in hot water with, at best, Costco, and at worst, Costco and the police"
When you scan your membership, the entire transaction ties to your account, including payment method information. If authorities trace a stolen card to your membership number, you must prove you didn't commit fraud-or face membership termination and potential criminal investigation. Costco's membership agreement explicitly prohibits sharing your card, and violation can result in permanent account closure with no option to rejoin.
- Scammers often pull up behind you and request membership scanning
- Costco pumps don't require ZIP codes because membership provides verification
- This allows thieves to test stolen cards without knowing the original owner's ZIP
- Even one-time scanning counts as membership sharing violation
- Over 80 million paid members exist, making Costco aggressive about protecting renewals
Historical Context: When Did This Policy Start?
Costco's Shop Card exception policy dates back to at least 2019, when the company formally codified that non-members may use Shop Cards for all purchases including gas. This aligned with federal law requiring retailers to accept gift cards from non-members under the Credit CARD Act of 2009. However, Costco maintains the right to require membership for obtaining Shop Cards in the first place, creating the current asymmetry.
Before 2021, some warehouses allowed non-members to purchase Shop Cards at the register, but after a card skimming attack exposed payment data at multiple locations, Costco tightened access controls. The breach affected thousands of customers and led to stricter verification for all transactions, including gift card purchases.
Final Verdict: Clever Hack or Dangerous Gamble?
The Shop Card Costco gas trick is technically functional but economically questionable for most people. It works as advertised at most warehouses, but the acquisition barrier, lack of rewards, and potential for pump failures make it inferior to simply paying the $60 annual Executive membership fee, which pays for itself after just 120 gallons of gas when factoring in the 2% reward.
The far more dangerous scenario involves membership card sharing scams, which have resulted in membership terminations and legal trouble for unsuspecting members. Always say no when strangers request you scan your card-no amount of politeness is worth risking your membership or legal standing.
For Amsterdam-area residents wondering about applicability: Costco operates no warehouses in the Netherlands, so this policy only applies to U.S., Canada, UK, Japan, Australia, and other countries where Costco physically operates gas stations.
Everything you need to know about Shop Card Loophole Costco Gas
Is the Shop Card gas trick worth it financially?
No, it's rarely worth it unless you receive the Shop Card as a genuine gift. The typical 5-15% premium paid to acquire Shop Cards from third parties exceeds Costco's gas savings advantage, and you miss the 5% cashback reward available to members.
Can you use a Shop Card if the gas costs more than the card balance?
No, not without a membership. The pump stops自动 at the card balance. To pay the difference, you must scan a membership card, which non-members don't have.
Does Costco charge extra for non-members using Shop Cards?
No, the gas price is identical for members and non-members paying with Shop Cards. However, non-members pay an implicit premium when buying Shop Cards from third parties.
Will Costco ban me if I use someone else's Shop Card?
No legitimate risk exists if you received the Shop Card legitimately as a gift. Costco only bans members caught sharing their membership card, not Shop Card recipients.
Can I reload a Shop Card without a membership?
No. Only Costco members can reload funds onto Shop Cards. Non-members can only use the existing balance until depleted.
Is this the only way non-members can get Costco gas?
Yes. The Shop Card is the only legal method for non-members to purchase fuel at Costco. Buddy systems (bringing a member) or fake memberships violate terms and risk termination.
