Most Costco members know the return policy is legendary. You can bring back a couch you bought two years ago, return a half-eaten rotisserie chicken, or swap out a mattress that turned out to be a mistake. The “Risk-Free 100% Satisfaction Guarantee” isn’t marketing fluff – for the vast majority of what’s sold at Costco, it holds up. That’s exactly why people keep renewing year after year, paying an annual fee just for the privilege of shopping there.
But the Costco return policy has real edges, and some of them will surprise you. Walk up to the returns counter with the wrong item and you won’t get a refund, no matter how long you’ve been a member, how politely you ask, or how nicely you explain the situation. The story is more complicated than what’s posted on Costco’s website – over the years, employees and shoppers have revealed plenty of unofficial quirks and hidden exceptions that many members don’t fully understand until they’re standing at the return counter.
On top of that, the returns experience itself has shifted. In 2026, some shoppers say things feel different at the counter. While Costco has not officially changed its guarantee, stricter enforcement and closer monitoring of return patterns have sparked confusion online. Knowing exactly which items fall into the non-returnable category before you buy them is the most useful thing a Costco shopper can do. Here are all 14.
1. Cigarettes
Costco does not accept returns on cigarettes or alcohol where prohibited by law. For cigarettes specifically, that prohibition effectively means everywhere. No US state permits the return of tobacco products to a retailer once they’ve been purchased. Costco sells cigarettes in bulk – often in cartons rather than individual packs – which means a buyer who discovers they don’t like a particular brand, or who decides to quit smoking, has no path to a refund.
This is a firm, no-exceptions rule. The packaging, the freshness of the product, none of it matters. If you bought cigarettes at Costco, you own them. Worth knowing before you stock up on a brand you haven’t tried, or buy a carton as a gift for someone else.
2. The Costco Return Policy on Alcohol (in Most States)
Alcohol is the most nuanced item on this list because the answer changes depending on where you live. Costco’s official position is diplomatic: “We do not accept returns on cigarettes or alcohol where prohibited by law.” Every state has different laws. As of 2026, states that generally prohibit alcohol returns include California, Georgia, Michigan, New York, New Jersey, Ohio, Maryland, North Carolina, Utah, and Wisconsin. States where Costco can generally accept unopened alcohol with a receipt include Texas, Washington, Florida, and Virginia (beer and wine only; spirits are state-controlled).
There’s also a lesser-known wrinkle: even in states where a physical return is prohibited, Costco may still issue a refund for a genuine quality problem – such as a spoiled or corked bottle – without taking the product back. The money returns; you dispose of the item yourself. That’s a narrow exception, not a general rule, but it does exist.
3. Electronics After 90 Days
While most items can be returned years later, Costco enforces a firm 90-day return window for specific high-value electronics and major appliances. This shorter window is designed to protect the retailer from rapid depreciation and “rental” behavior, where customers return gadgets as soon as a newer model is released. The 90-day clock begins on the day you receive the merchandise.
The 90-day limit applies to televisions, projectors, major appliances (refrigerators above 10 cubic feet, freezers, ranges, cooktops, over-the-range and under-counter microwaves, range hoods, dishwashers, water heaters, washers and dryers), computers, touchscreen tablets, smart wearable devices, cameras, aerial cameras (drones), camcorders, MP3 players, and cellular phones. Miss that window by a single day and the return option is gone. After 90 days, the only path for a defective device is the manufacturer’s warranty, not Costco’s returns counter. Open and test anything in this category as soon as it arrives, not two weeks later when the excitement of unboxing has worn off.
4. Costco Shop Cards
Shop Cards are non-refundable and cannot be exchanged for cash. That applies whether you bought the card for yourself, received it as a refund from a previous return, or picked it up as a gift. Once the value is loaded onto a Shop Card, it can only be spent at Costco – it cannot be reversed back into cash or credit.
This catches people off guard when they buy a Shop Card intending to use it as a gift and the recipient decides they don’t want a Costco membership. The card has value, but only within Costco’s ecosystem. If a non-member receives a Shop Card and can’t use it, their options are limited to giving it to someone who does shop there.
5. Gift Cards and Third-Party Tickets
Gift card and ticket items are non-refundable. Costco sells third-party gift cards – restaurant gift cards, spa packages, and similar – at a discount. The discount is real, but so is the risk: once purchased, the cards are yours whether or not you end up using them, and whether or not the business on the card has changed its terms or gone out of business entirely.
The same applies to tickets for events. If you buy a ticket bundle through Costco and plans change, neither Costco nor the event venue is under any obligation to refund you. Buy these with certainty, not optimism.
6. Airline Tickets
Airline and live performance event items are non-refundable. Costco Travel sells discounted airline tickets and vacation packages, and the savings can be genuine. But the trade-off is inflexibility. If your plans change after purchase, Costco’s return policy does not apply.
What you’re left with is whatever the airline’s own cancellation and change policy allows, which varies enormously by carrier, fare class, and how far in advance you try to make the change. In some cases you may be able to work directly with the airline. In others, you won’t. Before booking travel through Costco, it’s worth reading the airline’s specific terms, not just assuming the satisfaction guarantee will cover you if something goes sideways.
7. Live Performance Event Tickets
Live performance tickets purchased through Costco – concerts, theater shows, sporting events – fall under the same non-refundable rule as airline tickets. You can find it spelled out in Costco’s official return policy: event tickets and airline vouchers are non-refundable, no exceptions listed.
This matters because Costco occasionally sells ticket packages for major events at a discount. If the event is canceled or rescheduled, your options depend entirely on the venue or promoter – not on Costco. In the case of a full cancellation, most promoters do issue refunds directly to the original purchaser. But rescheduled events are a gray area, and Costco will not intervene on your behalf.
8. Precious Metals – Gold and Silver Bullion
Precious metals are non-refundable. Costco began selling gold bars to considerable fanfare in recent years, and demand has been strong. But every purchase is final. The logic is straightforward: precious metals fluctuate in value daily, which would create an obvious opportunity for arbitrage – buying when prices are low, returning when they go up. Costco closes that door entirely.
Gold bullion and silver are final sale. If you’re considering a precious metals purchase at Costco, go in knowing that you’re committing to ownership regardless of what happens to the market price afterward. The only possible avenue for recovery would be reselling through a third-party dealer or marketplace, not through Costco.
9. Special Order Kiosk and Custom-Installed Items
Custom products manufactured to a member’s personal and unique specifications cannot be returned or refunded, except for warranty repair or replacement due to failure to meet specifications. This covers a wide range of items ordered through Costco’s Special Order Kiosk program.
Custom orders from the Special Order Kiosk include HVAC systems, countertops, custom flooring, generators, solar panels, water heaters, and garage doors. These are manufactured to your specifications and cannot be returned except for warranty repair or replacement. If a contractor installs custom blinds cut to your window measurements, or a flooring crew lays hardwood cut to your room dimensions, there’s no undoing the transaction. These items are made to your specific home measurements, meaning they cannot be resold. The exception for warranty applies only if the product genuinely fails to meet the agreed-upon specifications – not if you simply change your mind about the color.
10. Digital Downloads (Once Accessed)
Digital content sold through Costco – software downloads, digital games, streaming subscriptions – is non-returnable once it has been accessed or redeemed. Once you’ve viewed or used the content, Costco has no way of taking it back, and the license has been transferred to you.
Be certain about any digital purchase before redeeming it. If you buy a digital software license as a gift and the recipient already owns it, the license cannot be returned. Check before you click “redeem.”
11. Tires and Batteries
Products with limited useful life, such as tires and batteries, may be sold with a product-specific limited warranty. Tires and batteries don’t fall under Costco’s standard satisfaction guarantee because they wear out predictably over time – returning them would be the equivalent of returning a candle you’ve already burned down. Instead, these products come with specific warranty programs.
Tires and car batteries fall under Costco’s separate auto-center warranty – typically five years on the battery and a road-hazard term on the tire. That means warranty claims involve different paperwork, different staff, and sometimes different outcomes than a simple return. If you have a tire or battery issue, bring it back – but expect to work through the warranty program rather than the standard returns desk.
12. Diamonds Over 1.00 Carat (Conditional Process, Not a Simple Return)
This one doesn’t mean you can never get your money back – it means the process is far more involved than walking up to the returns desk. Members returning a diamond over 1.00 carat must present all original paperwork, including IGI and/or GIA certificates, at which time they will receive a Jewelry Credit Memo. A Costco Graduate Gemologist then inspects the diamond within 48 hours before the refund is finalized. This isn’t a quick counter return – plan accordingly.
If you’ve lost your original GIA or IGI certification paperwork, the process becomes significantly more complicated. Keep that documentation stored somewhere safe the moment you get home.

13. Opened Software
Physical software – boxed programs sold on disc or with a license key card – cannot be returned once the packaging has been opened. This is a licensing issue rather than a Costco-specific policy quirk: once a software license is revealed and potentially used, Costco cannot legally resell it. The official policy hasn’t changed on this front, but Costco’s enhanced digital tracking now also helps identify repeat or suspicious return attempts.
The key word is “opened.” An unopened software box in its original sealed packaging may be returnable under the standard policy. The moment that seal breaks, the sale is final. If you’re buying software as a gift, confirm the recipient doesn’t already own it before you open the box.
14. Major Appliances After 90 Days
Major appliances get the same 90-day window as consumer electronics, and the same rule applies: miss the deadline and you lose the return option entirely. Electronics and major appliances must be returned within 90 days of receiving the merchandise.
This covers refrigerators, freezers, ranges, cooktops, dishwashers, washers, dryers, over-the-range microwaves, and water heaters. The 90-day clock starts from the date you receive the item, not the date you install it. If there’s any delay between delivery and installation – a renovation running long, a flooring project that isn’t finished yet – that time still counts. Some members have found themselves past the window before they even plugged the appliance in. Inspect and test appliances within days of delivery, not weeks.
What You Should Know Before You Shop
The 14 items on this list share a common thread: they’re either legally restricted, custom-made, time-sensitive, or tied to licenses that transfer the moment you use them. None of these exclusions are buried in fine print Costco is hiding – the exceptions are listed on the official policy page, but most people don’t think to read the return policy until they’re already holding something they want to give back.
According to Appriss Retail and Deloitte, fraudulent returns and claims cost U.S. retailers about $103 billion in 2024 – and Costco, with one of the most generous policies in retail, is an obvious target. While the official policy hasn’t changed, Costco is now utilizing enhanced digital tracking to prevent policy abuse. New entrance scanners link your visit to your account, making it easier for managers to identify high-frequency returners. Accounts with an unusually high percentage of returns compared to purchases may require manager approval for future refunds.
If a member’s account shows an unusually high volume of returns or a pattern of returning items after they have been heavily used, the account may be flagged for review. In extreme cases of abuse, a warehouse manager has the authority to cancel a person’s membership entirely. The policy is still among the most generous in retail, but it rewards members who treat it in good faith – not as a long-term rental service. Going in with accurate expectations about what you can return, what you can’t, and what the timeline looks like is still the best way to make the most of it.
