Costco Black Friday 2026: Sale Windows, Hours, Price Rules

Costco's 2026 Black Friday windows

Costco Black Friday 2026 is part of a longer Holiday Savings event that Costco dates from 30 October to 30 November. Costco splits it into five windows, and each item carries its own dates. The Black Friday items themselves run from Friday 27 to Monday 30 November. Warehouses are closed on Thanksgiving, Thursday 26 November, but Costco.com has its own set of online-only savings that day.

Two lines from Costco's own terms shape everything below. The prices shown are warehouse prices, and they may differ in Alaska, Hawaii, Puerto Rico, Costco Business Centers and online. And every deal runs while supplies last, with per-household limits on many items.

What is on sale now, 30 October to 15 November

The first window covers home, holiday and food items more than big electronics. Examples from Costco.com on 31 October: the Dyson Purifier Hot + Cool HP11 with $200 off, the Jackery 600v2 Solar Generator with $100 off, the Yale Assure Lock 2 Touch at $149.99 after $50 off, and the SimpliSafe 10-piece security system at $99.99 after $100 off, online only. Prices can change and stock runs out, so check the item page before you go.

Deals in the 27 to 30 November window

Costco has already published its Black Friday items, so you can plan now instead of waiting for an ad. These are some of the larger ones as Costco.com listed them on 31 October, with Costco's own labels for where each can be bought.

Costco's TV listings in this window include an Allstate 3-year protection plan bundle, which Costco says gives 5 years of total coverage. Costco also lists an Apple Savings Event for these four days (search AppleDeals26HM on Costco.com) without printing the prices in its overview.

Some items in this window show a second, earlier date on their listing, for example 16, 19 or 20 November. Read both dates on the item page before you plan around a 27 November start.

Thanksgiving Day, online only

On Thursday 26 November, with every US warehouse closed, Costco.com runs 10 online-only offers. They include a Samsung 100" Class QN80H Neo QLED TV at $4,499.99, an LG 85" Class NANO NU87 Series TV at $699.99, $300 off a Lenovo ThinkPad X1 Carbon 14" OLED laptop and $600 off a Lenovo IdeaPad Pro 5i 16" laptop. Restaurant and food gift cards are on the list too, such as a $100 inKind restaurant e-gift card for $64.99.

Is Costco open on Black Friday? Hours

Yes. Black Friday is not one of Costco's closure days, and its Black Friday window includes warehouse-only items from 27 November. Warehouses are closed on Thanksgiving Day: Costco's Black Friday page says so for 26 November 2026, and Thanksgiving is on Costco's list of days when every US warehouse closes, along with New Year's Day, Easter Sunday, Memorial Day, Independence Day, Labor Day and Christmas Day.

Costco has not published Black Friday opening hours. Its help pages say hours vary slightly by warehouse, and that the Find a Warehouse page and the Costco app show each location's hours, including any adjusted holiday hours. Pages that give one opening time for every Costco on Black Friday are guessing.

Executive members may be able to shop earlier: since 30 June 2025, Costco says, exclusive earlier hours for Executive members "may be available" at your local warehouse. Check your warehouse's store details to see whether yours offers them.

Costco price adjustments during the sale

If you buy something at Costco and it goes on sale later, Costco can refund the difference, but its Holiday Savings come with a dates rule. For items with specific sale dates, such as the Holiday Savings promotions, Costco says you must ask within both the promotion dates and 30 days of your purchase. A request made after the promotion has ended may be turned down.

• Bought in a warehouse: ask at the returns counter of the warehouse where you bought it.
• Bought on Costco.com: use the Request a Price Match form on Costco's help page. Costco says approved credits usually reach the original payment method within 5 to 10 business days.
• Limits: items with a promotional limit qualify only up to that limit, and precious metals are not eligible.
• What Costco does not do: it does not match other retailers' prices, and it does not match a lower warehouse price on a Costco.com purchase.

So if you bought a TV on 20 November and the same TV drops in the 27 to 30 November window, ask before the window closes on 30 November, not after.

Shopping Costco's Black Friday without a membership

Costco's terms say an active membership is required for warehouse purchases. Online, non-members can buy, but Costco adds a 5% surcharge over the posted member prices, except on prescription drugs. Adding a membership to your cart before checkout removes the surcharge.

Costco is also running an online-only offer for new members, valid through 20 December 2026: a $65 Digital Costco Shop Card when you apply and are approved for the Costco Anywhere Visa Card by Citi with a new Executive membership. Costco's conditions are that you set up auto renewal at sign-up, and that you are new to Costco or have not been a member in the last 18 months. It is a credit card offer, so read Costco's and Citi's full terms before you decide.

Returning Costco Black Friday buys

Costco's satisfaction guarantee covers most of what it sells, but the items people buy most on Black Friday have a time limit. Costco accepts returns within 90 days of the date you received them for:

• televisions and projectors;
• computers and touchscreen tablets;
• smart wearable devices, cameras, drones and camcorders;
• cell phones, where the carrier contract can change the return details;
• major appliances, such as refrigerators above 10 cu. ft., freezers, ranges, dishwashers, washers and dryers.

Some things cannot be returned at all, among them Costco Shop Cards, gift card and ticket items, and precious metals. Diamonds of 1.00 ct or more must come back with their original certificates.

Costco Cyber Monday 2026

Costco has a separate set of savings dated Monday 30 November, the same day the Black Friday window ends. All 10 items listed for the day on 31 October were online only. They include $100 to $600 off selected laptops and desktops (search PCDeals26HM on Costco.com), Hisense S7 Series CanvasTV models in 65" and 75" from $899.99 to $1,199.99, and $500 off a Whirlpool 24" dishwasher.

Cyber Monday offers from other stores will be on our Cyber Monday deals page, and Black Friday offers are on our Black Friday deals page.

How we checked

Every date, price and rule here comes from Costco's own pages, read from a US server on 31 October 2026: the Holiday Savings pages on Costco.com for each window, and Costco's customer service pages on price matching, holiday closures, hours, the non-member surcharge, returns and the new-member offer. We did not use ad scans or other websites. Costco's prices and stock change, so check the item page before you buy.
