# Costco Return Policy: Everything You Need to Know (2026)

Costco offers one of the most generous return policies in American retail: most items can be returned at any time, for any reason, with no receipt required. If you have a Costco membership, your purchase history is tied to your account, so you don't need to keep paper receipts.

There are a handful of exceptions — and knowing them will save you frustration at the returns desk.

Costco's General Return Policy#

Return window: Unlimited (for most items)

Costco's satisfaction guarantee applies to virtually all purchases:

  • No receipt required — purchases are tracked in your Costco account
  • No time limit — you can return items months or years after purchase
  • Refund method: Original form of payment (cash, credit card, check)
  • Membership refund: If you're dissatisfied with your membership, Costco will refund the full membership fee at any time

This policy applies to warehouse purchases and Costco.com orders alike.

Exceptions to Costco's Return Policy#

A few categories have specific limits:

Item CategoryReturn WindowNotes
Electronics (TVs, tablets, computers, cameras, smartwatches, drones)90 daysStrict 90-day limit; must be in original packaging preferred
Diamonds (1 carat or larger)48 hoursFor grading verification
Custom orders (engraved items, special orders)Limited — may not be returnableContact member services
Cigarettes and alcoholLimited — varies by state lawSome states prohibit alcohol returns
Airline/event tickets, hotel reservationsNon-refundableDigital/travel purchases often final
Hazardous materialsNon-returnablePesticides, pool chemicals, etc.
Cell phones/wireless90 daysSame as electronics

Most everything else: Unlimited return window. Furniture from 3 years ago, a blender you used twice, a jacket that doesn't fit — all can be returned.

What Counts as Electronics at Costco?#

Costco's 90-day electronics window covers:

  • Televisions (any size)
  • Laptop computers, desktop PCs, tablets
  • Smartphones and cell phones
  • Digital cameras and camcorders
  • Smartwatches and fitness trackers
  • Drones and aerial photography equipment
  • Projectors
  • Printers

Note: Monitors used as standalone displays (not part of a full computer system) may fall under the 90-day electronics rule. When in doubt, confirm with a Costco employee at purchase.

Can You Return Items Without the Original Packaging?#

Yes — generally. Costco does not require original packaging for most returns. Warehouse managers may ask for all parts and accessories to be returned (remotes, cords, manuals), but you don't need the box for most items.

Exception: For electronics, having the original box and all accessories makes the return process smoother and avoids restocking questions.

How to Return Items at Costco#

In-Warehouse Returns (Fastest Method)#

  1. Go to any Costco warehouse — not necessarily the one where you purchased
  2. Bring the item (and ideally the original packaging and accessories)
  3. Go to the Member Services desk (near the entrance/exit area)
  4. Present your membership card or the order number if you don't have the physical item
  5. Costco looks up your purchase in the system — no receipt needed
  6. Refund is processed immediately

You can return to any Costco location, not just where you originally bought the item. Costco has a national networked system.

Returning Online (Costco.com) Orders#

For items purchased on Costco.com:

  1. Return in-warehouse: Bring the item to any Costco warehouse for the fastest refund
  2. Return by mail:

- Go to Costco.com → Orders & Returns → Start a Return

- Select the items to return

- Print the prepaid return label

- Drop off at UPS

- Refund processes once Costco receives the return (5–7 business days)

Large items (furniture, appliances) ordered online: Costco may arrange a pickup. Contact member services for oversized items.

Returning Items You Received as a Gift#

If you received a Costco item as a gift:

  • You can return it to any Costco warehouse
  • You'll need the original purchaser's membership number or they can look it up by item/date
  • Refund goes back to the original purchaser's payment method (not cash to you, unless the original purchaser authorizes otherwise)

Costco Return Policy vs Competitors#

StoreGeneral Return WindowElectronics Exception
CostcoUnlimited90 days
Walmart90 days30 days (most)
Target90 days (RedCard: 120 days)15 days
Best Buy15 days (Elite/Elite Plus: 30/45)Same
Amazon30 days30 days
Sam's ClubUnlimited (with exceptions)90 days

Costco's policy is clearly the most generous for general merchandise. Walmart's 90-day window is solid for everyday items. Best Buy and Target have stricter electronics windows.

Does Costco's Return Policy Apply to Food?#

Yes — with some practical limits. If you're unhappy with a food item you purchased at Costco:

  • Bring back the unused portion or even just the empty package
  • Member Services will typically issue a full refund
  • This applies to fresh produce, packaged goods, and Kirkland Signature items
  • Costco's food court items are generally not refundable after purchase

Costco takes quality feedback on food seriously — returns signal product quality issues to the buying team.

FAQ#

Does Costco accept returns without a receipt?

Yes. Your Costco membership card links to your purchase history, so staff can look up any purchase without a paper receipt.

Can I return a TV to Costco after 90 days?

No — electronics including TVs have a strict 90-day return window. After 90 days, you would need to go through the manufacturer's warranty for defects.

Can I return a mattress to Costco?

Yes — mattresses fall under Costco's unlimited return policy (not electronics). Members have successfully returned mattresses months or even years after purchase.

What happens if I return too many items to Costco?

Costco monitors return patterns. Members who abuse the return policy (extremely high volumes or suspicious patterns) may have their membership revoked. In practice, reasonable returns for genuine reasons are always accepted.

Can I return a Costco membership?

Yes — Costco will refund your full membership fee at any time if you're dissatisfied, no questions asked.

Does Costco's return policy apply at all locations internationally?

Costco's return policy applies at all US warehouse locations. International locations (Canada, UK, Japan, etc.) have similar but slightly different policies — check your country's Costco website.

Can I return an item to Costco after 2 years?

For non-electronics, generally yes. Costco's unlimited guarantee means very old purchases can be returned — though staff discretion applies for items that are clearly worn out through years of use rather than defective.

Bottom Line#

Costco has the most generous return policy of any major US retailer: unlimited return window, no receipt needed, refund to original payment method. The key exception is electronics (90 days), so plan accordingly for TVs, computers, cameras, and similar items. For virtually everything else — furniture, clothing, food, appliances, tires — you can return at any time. Returns can be made at any warehouse location, not just where you bought.
