Costco Return Policy: Rules, Limits, Exceptions

Quick answer: Costco's return policy is famously simple: most items carry a "Risk-Free 100% Satisfaction Guarantee" with no strict time limit, according to Costco's official return policy page. The big exceptions are electronics, major appliances, and a handful of other categories that carry a 90-day window, plus a short list of items (like alcohol, cigarettes, and gift cards) that can't be returned at all in most locations. Membership fees are separately refundable at any time if you're not satisfied, per Costco's membership terms.

Key takeaways

• Costco's satisfaction guarantee has no set expiration date on most merchandise, but electronics, TVs, major appliances, smartphones, and a few other categories are limited to a 90-day return window, according to Costco's published policy.
• Non-returnable items typically include cigarettes and alcohol (where local law restricts it), diamonds over 1 carat sold as loose stones, custom or personalized products, gift cards, and gold bars.
• Costco can usually look up a purchase using your membership number even without a receipt, but bringing your receipt or packing slip speeds up any return significantly.
• A return is not the same as a price adjustment — if an item you already own simply drops in price within 30 days of purchase, you don't return anything; you request a price adjustment refund instead.

What does Costco's satisfaction guarantee actually cover?

Costco's return policy is built around one core promise: buy it, use it, and if you're not happy, bring it back — no expiration date required on most products. Costco describes this on its website as being "Risk-Free" with a 100% satisfaction guarantee, and it applies broadly across the warehouse, not just to a narrow list of categories.

This is unusual in retail. Most stores give you 30, 60, or 90 days and that's it. Costco's model is built on membership trust — you pay an annual fee to shop there, and the return policy is part of what you're paying for.

The philosophy is straightforward: Costco would rather take back a couch you decided you didn't like two years later than have a member feel stuck with a bad purchase. That said, "satisfaction guaranteed" doesn't mean "no exceptions." It means most non-electronic, non-restricted merchandise can be returned essentially any time, in reasonable condition, with proof of membership.

A few practical notes on how this plays out in warehouses:

• Returns are processed at the membership counter, not at a general customer service desk in most locations.
• Costco staff can decline a return if an item shows excessive wear inconsistent with normal use, even though there's no fixed deadline.
• Store credit or a refund to your original payment method is standard; how it's issued depends on how you originally paid.

Why do electronics and appliances only get 90 days?

Electronics, major appliances, and a few other product categories are capped at a 90-day return window because these items lose value fast and are more prone to buyer's-remorse returns after extended use, according to Costco's official policy. This exception exists specifically to prevent someone from using a TV for a year and then returning it right before a newer model comes out.

Costco's 90-day list generally includes:

• Televisions, projectors, and monitors
• Computers, laptops, and tablets
• Cameras and camcorders
• Smartphones and cell phones
• Major appliances (refrigerators, washers, dryers, and similar)
• Drones and certain smart-home electronics

The 90-day clock starts on the date of purchase (or delivery, for larger appliances), not the date you open the box. If you're past that window, the item generally isn't eligible for a standard merchandise return — but that's a different clock entirely from the separate 30-day price adjustment window, which we've broken down in detail in Costco Price Adjustments on Electronics: Special Rules You Should Know. Those two timelines get confused constantly, and it's worth understanding both if you buy electronics at Costco regularly.

Don't skip this: the 90-day return limit and the 30-day price adjustment window are two completely separate rules. Missing a return deadline doesn't affect your price adjustment eligibility, and vice versa — they're tracked independently from your purchase date.

What can't you return to Costco at all?

A short list of items is excluded from returns entirely, mostly due to law, safety, or the nature of the product itself. According to Costco's published policy, these typically include:

• Cigarettes and other tobacco products
• Alcohol, where restricted by state, provincial, or local law
• Diamonds valued at 1 carat or larger (these usually require a separate appraisal process)
• Custom-made or personalized items, like customized furniture or engraved products
• Gift cards
• Gold bars and certain precious-metal products

Alcohol is the trickiest one because rules vary so much by location. In many U.S. states, alcohol returns are restricted or banned outright by state alcohol-control laws, not just Costco policy — so a warehouse in one state may handle it differently than one in another. Costco Canada, for example, does not sell alcohol at all in most provinces due to separate provincial liquor retail rules, so the question doesn't even come up the same way north of the border.

Speaking of Canada — a few other differences are worth flagging for members who shop cross-border or move between the two countries:

Category	Costco U.S.	Costco Canada
Core satisfaction guarantee	No set expiration on most items	Same general policy, no set expiration
Electronics/appliances window	90 days	90 days
Alcohol returns	Varies by state law	Not typically applicable; alcohol sales handled under provincial rules
Membership fee refund	Full refund anytime, per Costco policy	Full refund anytime, per Costco policy
Gift cards / Costco Shop Cards	Non-returnable	Non-returnable

If you split time between the U.S. and Canada or shop both, always confirm the current rule with your local warehouse's membership desk — provincial and state laws shift, and Costco's own exception list is updated periodically.

Do you need a receipt to return something to Costco?

No — Costco can usually locate your purchase electronically using your membership number, even if you've lost the paper receipt. Every purchase is tied to your membership account, so the return desk can pull up your purchase history on the spot in most cases.

That said, bringing documentation still makes the process faster and reduces any chance of a dispute over price or purchase date. Here's a quick checklist for a smooth return:

• Bring your membership card (physical or in the Costco app)
• Bring the original receipt if you still have it
• Bring the item itself, along with original packaging when possible for electronics
• Bring any accessories, cables, or manuals that came in the box
• Have your ID ready in case the membership desk needs to verify identity

For big-ticket electronics or appliances, having the original box and accessories matters more, since the 90-day category is scrutinized more closely than general merchandise.

In-store returns vs. Costco.com: how the process differs

Returning something bought in the warehouse is different from returning something ordered on Costco.com, mainly in how the item gets back to Costco. In-store purchases go back to the membership desk directly. Online orders are typically returned by mail through a prepaid shipping label, by dropping the item at a warehouse, or in some cases through a scheduled pickup for large items like furniture or appliances.

A few things to expect with Costco.com returns specifically:

• Smaller items usually ship back using a return label generated through your Costco.com account
• Large or bulky items (furniture, big appliances) may qualify for at-home pickup instead of shipping
• Refund timing for online returns can take longer than in-store, since it depends on the item being received and processed by the warehouse or return center
• Some online-only items, like certain third-party marketplace products sold on Costco.com, may follow the third-party seller's return terms instead of Costco's standard policy

We've mapped out what to expect at each stage of an online return, including realistic refund timing, in Costco.com Online Order Refunds: What to Expect Step by Step. It's worth a look before you order anything large online, since delivery and pickup logistics for furniture and appliances differ quite a bit from a simple mailed return.

Can you get your membership fee back too?

Yes — Costco's membership fee is covered by the same satisfaction guarantee and can be refunded in full at any time if you're not happy, according to Costco's membership terms. You don't need to be canceling for a specific reason; if you decide the membership isn't worth it, the annual fee is refundable, including partway through your membership year in most cases.

This matters for return privileges too: canceling your membership doesn't retroactively void returns you're entitled to on items you already bought, but you generally need an active membership (or a same-day guest pass situation) to process new transactions and returns at the counter. If you're an Executive member weighing whether to downgrade, it's worth understanding how that decision interacts with any pending 2% reward or price adjustment — a topic we cover in How Costco's Executive Membership Rewards Interact With Price Adjustments.

Returns vs. price adjustments: which one do you actually need?

If the item is broken, unwanted, or not what you expected, that's a return. If the exact same item you already bought simply dropped in price, that's a price adjustment — and you don't return anything at all. This distinction trips up more shoppers than any other part of Costco's policy, because the two processes look similar but solve completely different problems.

Here's the difference in plain terms:

Situation	What it's called	What happens
Item is defective, unwanted, or wrong	Return	You bring it back (or ship it) and get a refund or exchange
Same item drops in price within 30 days of your purchase	Price adjustment	You keep the item; Costco refunds the price difference
Item is on final sale, custom, or excluded from returns	Neither applies	Check the specific item's exception rules

Costco's price adjustment window runs 30 days from the original purchase date, according to Costco's policy, whether the drop happens through a weekly sale, a coupon book promotion, or a warehouse markdown. We go deep on exactly what starts and stops that 30-day clock in The Costco Return Window Explained: Your 30-Day Price Adjustment Timeline and What Triggers Refund Eligibility, and cover the full mechanics of claiming one in The Complete Guide to Costco Price Protection.

The catch is that Costco doesn't automatically flag price drops for you. You have to notice the drop yourself and bring your receipt in, or check Costco.com, within that 30-day window — which is exactly the gap CostRefund is built to close, by scanning your receipts and sending an alert the moment something you bought drops in price, whether you're shopping Costco U.S. or Costco Canada.

Track your returns and your refunds in one place

Knowing the return rules is half the battle — the other half is not leaving money on the table when a price drops on something you already own. CostRefund tracks your 30-day price adjustment window automatically after you scan a receipt, and sends an instant alert the moment an eligible item drops in price, so you're never manually rechecking prices on things you bought weeks ago. Members also use it to spot in-store warehouse markdowns and see what other shoppers nearby are finding — turning routine Costco trips into something closer to a game. Check your eligible refunds at CostRefund before your next warehouse run.
