Costco Electronics Return Policy: The 90-Day Rule Explained

Quick answer: Costco gives you 90 days from the date of purchase to return most electronics — TVs, computers, laptops, tablets, projectors, smartwatches, and similar items — according to Costco's published member policies. This is shorter than Costco's general "Risk-Free 100% Satisfaction Guarantee" return window, which has no set time limit for most other merchandise. The 90-day clock is separate from the 30-day price adjustment window, and mixing the two up is the single most common mistake shoppers make.

Key takeaways

• Electronics get a firm 90-day return window, unlike most other Costco products which can be returned anytime under the general satisfaction guarantee.
• The 90-day rule covers TVs, computers, laptops, tablets, cameras, projectors, drones, and most other electronics, according to Costco's return policy.
• A return gives you your money back or a swap; a price adjustment gives you the difference back on the item you already own — they run on different clocks and different rules.
• Some electronics categories have their own added rules on top of the 90 days, so check the specific product type before assuming a standard return applies.

Step 1: Confirm your item actually falls under the 90-day rule

Not everything sold in the electronics department gets the 90-day treatment — check the item type first. Costco's published policy applies the 90-day limit specifically to televisions, computers, laptops, tablets, smartwatches, cameras, drones, and projectors.

Accessories sold alongside electronics — think phone cases, cables, or basic peripherals — often fall back under Costco's general return guarantee instead, which doesn't carry the same 90-day cutoff. If you're not sure which bucket your item lands in, the safest move is to ask a Costco member services associate before you leave the checkout line, or check the receipt, which usually flags special return terms.

A few categories get extra conditions layered on top of the 90 days:

• Appliances often need to be returned in working condition with all original parts, and some major appliances have their own separate rules — worth a look if you're returning a large kitchen or laundry item.
• Furniture items sometimes have condition requirements distinct from small electronics.
• Mattresses run on their own separate policy entirely — we cover that in Costco Mattress Return Policy: What to Know.

Step 2: Track the purchase date, not the "open box" date

The 90-day countdown starts on your purchase date, according to Costco's return policy — not the day you opened the box, set up the TV, or first turned on the laptop. This trips people up constantly, especially with big electronics that sit in a closet for a few weeks before installation.

Practical example: you buy a 65-inch TV on July 1. You don't get around to mounting it until August 15. Your return window still closes around September 29 — 90 days from the purchase, not from the day you finally used it.

• Save your receipt or check your Costco.com order history for the exact purchase date.
• Set a personal reminder around day 80 if you're on the fence about keeping the item.
• Don't assume "still in the box" resets any clock — it doesn't, per Costco's published policy.

Step 3: Know what a return actually gets you (versus a price adjustment)

A return under the 90-day rule gets you a refund or exchange for the item itself — not money back on an item you're keeping. This is where a lot of confusion starts, because Costco also offers something called a price adjustment, and the two get mixed up constantly.

Here's the difference in plain terms:

	Electronics Return	Price Adjustment
What you get	Full refund or exchange	Difference credited back
You keep the item?	No — you give it back	Yes — you keep it
Time window	90 days from purchase	30 days from purchase
Applies when	Item is defective, unwanted, or unsatisfactory	Same item drops in price at Costco
Where to do it	In-store or by mail for online orders	In-store or online, per Costco's process

If your TV works fine but the price dropped $150 two weeks after you bought it, that's not a return situation — that's a price adjustment. We break down exactly how that process works in Costco Price Adjustment on Electronics and Appliances, and the general rules across every category are in Costco Price Adjustment Window by Category: The Full Chart.

Don't skip this: the 90-day return window and the 30-day price adjustment window are two separate clocks that start on the same day. Missing the shorter 30-day window doesn't extend your return rights, and a successful return doesn't affect a price adjustment you already claimed — but you can't do both on the same transaction once the item's been returned.

Step 4: Gather what you need before you head to the returns desk

Bring your receipt or order confirmation, your Costco membership card, and the item itself with as many original parts as you have. Costco's policy doesn't require a receipt for most returns since purchases are tied to your membership account, but having it speeds things up considerably and helps avoid any confusion about the purchase date.

• Bring your Costco membership card — purchases are linked to your account either way.
• Bring the receipt or pull up your online order if you have it, even though it's not strictly required.
• Bring original packaging, cables, remotes, and manuals if you still have them.
• Note any visible damage or defect so you can describe it clearly.
• Check whether the item needs factory reset (laptops, tablets) before handing it over.

If you bought the item online rather than in-warehouse, the process differs slightly — some online electronics returns go through mail-back rather than an in-warehouse desk. Check your online order details for the specific return method Costco offers for that purchase.

Step 5: Handle the no-receipt or lost-order scenario

You can still often return electronics without a physical receipt, because Costco ties purchases to your membership number. Staff can typically look up the transaction using your membership card at the register or service desk, according to Costco's published policy.

This matters more for electronics than for cheaper items, since the 90-day clock still applies whether or not you have paper proof — an associate needs to confirm the purchase date to know if you're inside the window. If your membership account shows the purchase, you're generally fine. If Costco can't locate any record of it, the return may not be possible, so it's worth registering high-value electronics purchases to your online account when you buy them, if that option is offered.

Step 6: Know how country differs if you're shopping Costco Canada

The 90-day electronics rule applies in both the US and Canada, but always confirm current details with your local warehouse since specific terms can vary by region. Costco Canada publishes its own return policy separately from Costco US, and while the general structure — a defined electronics window shorter than the open-ended standard guarantee — is consistent, small details like documentation requirements or restocking conditions on certain categories can differ.

If you're a Costco Canada shopper, don't assume every U.S. return detail applies word-for-word. When in doubt, ask your local Costco membership counter or check Costco.ca directly for the current wording.

What to do next

If you're inside the 90-day window and the item just isn't working out, don't wait — bring it back with your card and whatever documentation you have. If the item's fine but you suspect the price has dropped since you bought it, that's a different move entirely, and it's worth checking Costco Price Adjustment In-Store: What to Expect so you know what to say at the desk.

This is exactly the gap CostRefund was built for. You upload your receipt, and CostRefund keeps watching that item's price for the 30 days after your purchase — completely separate from your 90-day return rights — and flags it the moment it looks like you might be owed money back. CostRefund identifies potential price-adjustment opportunities; Costco makes the final call on eligibility and approval. It won't help with a broken TV, but it'll make sure a price drop on a working one doesn't slip past you.

Checklist: Returning electronics to Costco within 90 days

• Confirm your item type qualifies under the 90-day electronics rule, not the general guarantee.
• Check your purchase date on the receipt or online order history.
• Bring your Costco membership card to the returns desk or service counter.
• Gather original packaging, cables, remotes, and manuals if available.
• Factory reset laptops or tablets before returning them, if applicable.
• Ask an associate to confirm your specific item's return terms if you're unsure.
• Check Costco.ca for Canada-specific wording if you're outside the US.
• Consider a price adjustment instead of a return if the item works fine but cost less later.
