Costco deep dive

Costco has no holiday return deadline because it has no return deadline. Except for the list that matters most at Christmas.

Terms examined Aug 29, 2026 4 min read The 90-day list is the whole story
No deadline for most merchandise, any time of year. The holiday question only exists for the 90-day electronics list.

Costco’s guarantee has no stated day count, so it needs no seasonal extension. What holiday shoppers actually need is the list of what runs on 90 days, quoted below in full.

Here is Costco’s entire published rule for general merchandise:

Quoted from Costco

“On Merchandise: We guarantee your satisfaction on every product we sell, and will refund your purchase price*, with the following exceptions:”

No number of days appears anywhere in it. Not 90, not 365, nothing. A gift bought in October is under the same open-ended guarantee in January, which is why Costco publishes no holiday extension: for most items there is no window to extend. As of August 29, 2026, a search of the page for holiday, Christmas and December matches nothing but a footer link to store hours. The asterisk is worth knowing about too: it resolves to Limitations apply. See the membership counter or Costco.com for details, so the guarantee’s outer limits live off the page that states it.

The exception that decides Christmas: the 90-day list

Quoted from Costco

“Electronics: Costco will accept returns within 90 days (from the date the member received the merchandise) for Televisions, Projectors, Major Appliances (refrigerators above 10 cu. ft., 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 (return details will vary by carrier service contract).”

Read the parenthetical, because electronics is doing a lot of hiding: washers, dryers, dishwashers and water heaters are on the same 90-day clock as a television. And the clock runs from the day the member received the item, not from Christmas.

What 90 days from receipt means for gift timing

Received Oct 15 A TV or appliance bought early for Christmas 90 days ends ~Jan 13, three weeks after the unwrapping
Received Nov 28 The Black Friday version of the same purchase 90 days ends ~Feb 26, no pressure at all

That is the entire holiday strategy for Costco: on 90-day items, buying later gives the recipient more time, which is the opposite of the instinct that grabs the September deal. For everything off the list, buy whenever you like; no clock is running.

The gifts with no guarantee at all

The same page lists categories that cannot come back, and several are exactly what people give in December: Gift Card and Ticket items are non-refundable, Shop Cards are non-refundable, Precious metals are non-refundable, Airline and Live Performance Event items are non-refundable, and custom special-order product cannot be returned or refunded, except for warranty repair/replacement due to failure to meet specifications. Concert tickets and gold jewelry are done at purchase.

The receipt question the page never answers

The word receipt appears nowhere on Costco’s return policy page. It states where returns happen, and nothing about proving the purchase:

Quoted from Costco

“Products purchased at a Costco location need to be returned at the returns counter at any Costco warehouse. Items ordered online can be returned at any Costco warehouse -or- you can initiate a return through Costco.com.”

So this page cannot promise you a receipt-free gift return, and we will not promise it either. What the published text does establish: returns run through the warehouse counter, purchases are tied to membership, and for a gift the clean path runs through the member who bought it. Our full breakdown of the year-round rules is at the Costco return policy, examined.

Watch this space in late October. Retailers publish season-specific return pages as the holidays approach. Costco had none as of August 29, 2026; if one appears, we re-read everything quoted here and update this page under a fresh date.

Questions people actually ask

Can I return a Christmas gift to Costco in February?

If it is off the 90-day list, yes, the guarantee has no stated deadline. If it is on the list, count 90 days from the day it was received and check the calendar, not the season.

Does Costco take back opened electronics?

The 90-day clause does not distinguish opened from unopened; the deadline is the only stated test. Carrier-contract phones are the exception, where return details will vary by carrier service contract.

Is there a restocking fee?

None appears anywhere on the published page. No return-shipping deduction is stated for online returns either.

What about diamonds?

Over 1.00ct, bring the paperwork: Members returning a diamond over 1.00ct must also present all original paperwork (IGI and/or GIA certificates), after which a Costco Graduate Gemologist inspects within 48 hours. The refund starts as a Jewelry Credit Memo.
