Costco built its reputation on one of the most generous return policies in retail. The Costco return policy is grounded in a Risk-Free 100% Satisfaction Guarantee: if you are unhappy with a product or even your membership, Costco will refund your purchase, no questions asked.
Most items carry no time limit. Electronics and major appliances have a 90-day return window. And your membership itself can be cancelled for a full refund at any time. That is a level of consumer confidence that very few retailers come close to matching.

The Satisfaction Guarantee: What It Actually Means
Costco’s core promise is simple. If a product does not satisfy you, whether that is a jacket that pills after two washes, a piece of furniture that fell apart, or food that tasted nothing like expected, you can return it. There is no time limit for most merchandise. You do not need the original packaging. You do not need a receipt. Your membership card serves as your purchase record because Costco’s system links every transaction to your account.
This applies equally to items bought in a Costco warehouse and on Costco.com. Online purchases can be returned to any warehouse location or shipped back using a return label generated through your account.
The 90-Day Electronics Exception
Electronics are the most significant exception to Costco’s unlimited return window. The following categories must be returned within 90 days from the date you received the item (not the purchase date, which matters for shipped orders):
- Televisions and projectors
- Computers, laptops, and desktops
- Touchscreen tablets
- Cameras and camcorders, including aerial cameras (drones)
- Cellular phones (return conditions may vary by carrier contract)
- Major appliances including refrigerators above 10 cu. ft., freezers, ranges, cooktops, dishwashers, washers, and dryers
- Smart wearable devices and MP3 players
Costco introduced this 90-day window specifically to prevent customers from using expensive electronics for a short period and then returning them. After the window closes, Costco Concierge Services offers free technical support, and the manufacturer’s warranty continues to apply. Costco also automatically extends the manufacturer’s warranty to 2 years on TVs, computers, and major appliances purchased with your membership.
Items That Cannot Be Returned to Costco
The satisfaction guarantee does not cover everything. The following items are non-returnable:
- Cigarettes and tobacco products (state law restrictions apply)
- Alcohol in states where return is prohibited by law
- Costco Shop Cards (gift cards) cannot be returned or redeemed for cash
- Airline tickets and live event tickets are non-refundable
- Gold and silver bullion and precious metals cannot be returned
- Special Order Kiosk and Custom Installed Programs including custom flooring, countertops, HVAC, and solar panels manufactured to your specifications
- Digital downloads once accessed cannot be returned
How to Return Items to Costco
In-Warehouse Returns
Bring the item to the customer service desk at any Costco warehouse, not necessarily the one where you purchased it. Have your membership card ready. Staff will look up your purchase in the system. Original packaging is preferred but not required for most items. Refunds are processed immediately and credited to your original payment method.
Online Returns via Costco.com
Log into your Costco.com account and navigate to your order history. Select the item you wish to return and follow the prompts. You will receive a prepaid return label or be directed to bring the item to a warehouse. Online return refunds typically process within 2 to 3 business days after Costco receives the item. Costco also refunds original shipping and handling fees on online orders.
Returning Large Items
Freight-delivered items, including large furniture and major appliances, require separate return coordination. Contact Costco’s customer service to arrange pickup. For online mattress purchases, Costco arranges a free pickup service so you do not need to transport a large mattress yourself.
Returning Without a Receipt
Costco’s purchase tracking system means receipts are almost never required. Every transaction is linked to your membership account. Staff at the returns desk can pull up any purchase using your membership card or number. The Costco mobile app also stores digital receipts for recent purchases, which can speed up the process.
If you received an item as a gift and do not have a membership, you can still return the item by presenting the original receipt or gift receipt along with a government-issued ID.
Costco’s 30-Day Price Adjustment Policy
If an item you purchased goes on sale at Costco within 30 days of your purchase date, you are entitled to a price adjustment refund for the difference. You do not need to return the item. Visit the customer service desk with your receipt or membership card and ask for the adjustment. This applies to both in-warehouse and Costco.com purchases.
Membership Returns
If you are ever dissatisfied with your Costco membership, you can cancel it at any time and receive a full refund of the annual membership fee. This applies whether you are a Gold Star or Executive Member. To cancel, speak with a team member at any warehouse or call Costco’s Member Services Center at 1-800-774-2678.
2026 Enforcement Changes
While Costco has not officially changed its written return policy, enforcement has tightened noticeably at many warehouses in 2025 and 2026. Warehouses now use membership scanning systems at entrances that link purchase history. Manager approval may be required for flagged accounts. Perishable food returns now require physically bringing the item to the store rather than simply calling to report dissatisfaction. Members who show patterns of excessive or suspicious returns may have their memberships reviewed and, in rare cases, cancelled. The annual membership fee is refunded if a membership is revoked.

Frequently Asked Questions About the Costco Return Policy
1. Can I return a TV to Costco after 90 days?
No. Televisions are electronics and fall under the firm 90-day return window. After that window closes, your options are the manufacturer’s warranty and Costco’s Concierge Technical Services for support.
2. Do I need a receipt to return something to Costco?
No. Costco tracks every purchase through your membership account. Bring your membership card to any warehouse and staff can pull up your purchase history. Receipts are helpful but not required for most returns.
3. Can I return food to Costco if I have already opened or partially eaten it?
Yes. Food items, including partially consumed products, fall under the satisfaction guarantee. Bring the remaining product to the customer service desk. In 2026, perishable returns require you to bring the item physically to the store rather than reporting it by phone.
4. What happens if Costco cancels my membership for too many returns?
Costco will refund your full annual membership fee if they cancel your membership. The membership itself is non-transferable, and once revoked, you will lose warehouse access. This outcome is reserved for extreme or repeated abuse of the return policy.
5. Can I return a Costco item at a warehouse different from where I bought it?
Yes. Costco accepts returns at any warehouse location, regardless of where the item was originally purchased. The return is processed through your membership account, so location does not matter.
Why the Costco Return Policy Stands Apart in 2026
The Costco return policy remains the most generous in retail by a meaningful margin. No time limit on most merchandise, no receipt requirement, and a membership-level refund guarantee create a shopping environment where major purchases carry genuine peace of mind.
The 90-day electronics window is the one place where Costco aligns with normal retail expectations, but it still outpaces many competitors in that category. Returning before deadlines for electronics, knowing the non-returnable list, and using the 30-day price adjustment option all help you get the most from your membership.
