Best Buy vs Costco electronics 2026

Returns, warranty and price matching compared, so you know which store's rules fit the TV or laptop you are buying.

The bottom line

For a big-ticket electronics purchase, Costco's rules protect you more: 90 days to return most electronics and a manufacturer warranty extended to up to 2 years on TVs and computers. The catch is that you need a membership. Best Buy gives only 15 days to return (60 for paid members), but it price matches identical items from many stores, except during Black Friday week. Costco often sells TVs under model numbers other stores do not carry, so compare specs, not just prices.

Side by side

	Best Buy	Costco
Standard return window	15 days from receipt	90 days from the date you received it, for TVs, computers, tablets, cameras and most other electronics
Longer return window	60 days for My Best Buy Plus and Total members	Not needed
Membership cost	Not required to shop. Plus is $29.99 a year and Total is $199.99 a year (since June 4, 2026)	Costco membership required to buy (see Costco for current fees)
Warranty	Manufacturer's warranty. Geek Squad Protection is an optional paid plan	Extends the manufacturer's warranty to up to 2 years on TVs, projectors, computers and major appliances, at no extra cost
Price matching	Matches identical items from listed competitors, including Amazon, Walmart and Costco	Not covered in our sources
Black Friday week	Price Match Guarantee excludes items on sale the Thursday before Thanksgiving through the Monday after, and Black Friday pricing	The 90-day return window already covers the holidays

Costco says some items, such as Apple devices, must be factory reset and unlocked before you return them. It also says repeated or excessive electronics returns can lead to account review.

Might want to return it after a month	Costco	Best Buy's standard window is 15 days. Only paid members get 60.
Want a price match	Best Buy, outside Black Friday week	It matches identical items from listed stores, but not from the Thursday before Thanksgiving through the Monday after.
Want a paid plan that covers screen pixel problems	Best Buy	Geek Squad Protection lists pixel and ghost-image repair for TVs. It costs extra.
Do not have a Costco membership	Best Buy	You can buy without paying a membership fee. Check Best Buy's 15-day window first.

Trap 1: the Costco model number

Costco often sells TVs with model numbers that other stores do not carry. Reporting on this says it makes price comparing and price matching hard, because Best Buy only matches the identical brand and model number. Costco's versions can include extras, such as an added remote or warranty on one Sony model, but they may also have fewer features than the standard model.

Compare the two spec sheets line by line. Our Black Friday TV buying guide shows which specs to check.

Trap 2: price matching in Black Friday week

Best Buy's Price Match Guarantee excludes items for sale the Thursday before Thanksgiving through the Monday after. It also excludes Black Friday pricing, clearance, open-box and refurbished items, and marketplace sellers. If you want a match, ask outside that window. See how the big stores compare on TVs in Best place to buy a TV on Black Friday.

Trap 3: old credit card perks

Some older articles say the Costco Anywhere Visa adds two more years of warranty. Reporting says Citi ended that benefit in January 2023. Check your card's current benefits guide instead of relying on old coverage.

Before you check out

Write down the return deadline the day you buy: 15 days at Best Buy (60 for paid members) or 90 days at Costco.
Copy the exact model number and compare specs if you are weighing a Costco model against a Best Buy one.
If you want a price match, check the date against Best Buy's Thanksgiving-week exclusion.
Decide if you want a paid protection plan. Get the price for your exact item at checkout.
Keep the box and receipt until the return window ends, then test the screen or laptop right away.

How we put this guide together

We don't test products or stores. On October 9, 2026 we compared Best Buy's published return, price match and protection plan pages with Costco's policies as described in the reporting listed below. Costco's own pages were not available to us, so confirm Costco's current terms and membership fees before you buy. Store policies change.

Quick answers

Which has the better return policy, Best Buy or Costco?

Costco, for most electronics. It gives 90 days from the date you received the item. Best Buy gives 15 days, or 60 days for My Best Buy Plus and Total members.

Does Costco really extend the warranty on TVs?

Yes. Costco says it extends the manufacturer's warranty for up to two years on items such as TVs, projectors, computers and major appliances. You can add an Allstate protection plan to reach up to five years.

Will Best Buy match a Costco price?

Costco is on Best Buy's list of qualified competitors, but the item must have the identical brand and model number. Many TVs at Costco have model numbers that other stores do not sell, so a match is often not possible. Best Buy also pauses price matching from the Thursday before Thanksgiving through the Monday after.

Does Best Buy charge a restocking fee on TVs?

Not by its published policy. Best Buy lists 15% fees on items such as cameras, drones and projectors, and a $45 fee on activatable devices like phones. No fees apply in some states. Check the current policy before you buy.

Are Costco TVs the same as Best Buy TVs?

Not always. Costco often sells TVs with model numbers that other stores do not carry. Some have extras, and some may have fewer features than the standard model. Compare the spec sheets.
