Costco has one of the most generous return policies in retail — most items can be returned at any time, for any reason, with no time limit. But it's not truly unlimited. Electronics, cigarettes, alcohol, and a handful of other categories have specific rules. Here's the complete breakdown.
Costco will refund your membership fee in full if you are dissatisfied with it for any reason. For products, most items have no formal return deadline — but "any time" isn't always practical, and a few categories have strict limits.
Costco Return Windows by Category
| Category | Return Window | Notes |
|---|---|---|
| Most items | No time limit | Clothing, furniture, appliances, home goods, food, etc. |
| Electronics | 90 days | TVs, computers, cameras, projectors, smartwatches |
| Major appliances | 90 days | Washers, dryers, refrigerators, dishwashers, ranges |
| Jewelry | No time limit | Diamonds over $1,500 require professional appraisal |
| Cigarettes & alcohol | ❌ No returns | State laws prohibit returns in most jurisdictions |
| Special orders | ❌ Final sale | Custom-ordered items generally cannot be returned |
| Airline & travel tickets | ❌ No returns | Subject to provider's cancellation policies |
| Gift cards | ❌ No returns | Cannot be returned or exchanged for cash |
| Costco auto program | Varies | Subject to dealer's policy |
Costco reserves the right to refuse returns on items that show excessive wear or that were clearly used for years before being returned. The policy exists for customer satisfaction — not to be abused. Returning a 5-year-old TV is unlikely to be accepted, even though there's technically no time limit.
Electronics: The 90-Day Window Explained
Costco's 90-day electronics window is actually the best in retail — most competitors give you 15–30 days. The 90-day clock starts from the date of purchase (or delivery for Costco.com orders). Items covered include:
- Televisions (all sizes)
- Laptops and desktop computers
- Tablets and e-readers
- Digital cameras and camcorders
- Projectors
- Smartwatches and fitness trackers
- GPS devices
- Cell phones (check carrier policy too)

Costco Concierge Services for Electronics
Costco offers a free service called Costco Concierge Technical Support for televisions and most consumer electronics. This gives you free technical support by phone beyond the manufacturer's standard support period. It's worth calling before initiating a return if you're having technical issues — they may be able to fix the problem remotely.
Does Costco Track Returns?
Yes. Costco monitors return patterns by membership account. Returning an unusual number of items — especially expensive ones — can flag your account. Repeat abuse of the return policy can result in Costco cancelling your membership. The policy is meant for genuine dissatisfaction, not to use products for extended periods and return them.
Frequently Asked Questions
Do I need a Costco membership to make a return?
Yes. Returns are tied to your membership account. If you received an item as a gift, the original purchaser would need to initiate the return, or you can visit the warehouse and they'll work with you.
Can I return a Costco item to any warehouse location?
Yes. You can return to any Costco warehouse in the country, not just the one where you purchased the item.
What happens to my Costco membership if I return a lot of items?
Excessive or abusive returns can result in membership cancellation. Costco monitors return behavior — especially for high-value items. Returning items in genuinely used or damaged condition after years of use is the type of abuse that can trigger account review.
Can I return food items to Costco?
Yes — Costco accepts returns on most food items with no time limit if you're not satisfied. Bring what's left of the product along with the packaging if possible.
Can I return a Costco mattress?
Yes. Mattresses fall under the "most items — no time limit" policy. Costco is known for accepting mattress returns even after months of use, though the same abuse warnings apply.
