The Costco Black Friday Complete Guide 2026: Every Deal Wave, Every Strategy and Why You Should Shop Before November

Most people think Black Friday at Costco means going to Costco on Black Friday.

The members who capture the best Costco Black Friday deals do something different. They go to Costco in late October.

This is the most commercially significant insight in the entire Costco Black Friday playbook: the same deals that generate weekend crowds and sold-out inventory on the Friday after Thanksgiving are available — at the same prices, with full inventory — four to six weeks earlier. And the members who know this arrive to find the exact item they want, in the exact configuration they need, with no competition, no crowds, and no risk of selling out.

This guide covers everything about Costco's Black Friday event in 2026 — the deal wave structure, the specific categories that generate the deepest discounts, the Holiday Savings Book that arrives in October, the Thanksgiving Day warehouse closure, the Cyber Monday online component, and the complete shopping strategy that experienced members use to capture every available Black Friday savings opportunity without the Black Friday experience.

How Costco's Black Friday Event Actually Works: The Wave Structure

Costco's Black Friday promotional event is not a single day of deals. It is a multi-week promotional structure that typically unfolds in phases across October and November — with each wave delivering specific categories of deals at promotional pricing that holds across the entire wave period.

The 2025 Black Friday structure provides the most current reference for what to expect in 2026:

The Holiday Savings Book arrived in members' mailboxes during the week of October 19. This is Costco's separate Black Friday promotional catalog — distinct from the regular monthly Member Savings coupon book — covering the full range of holiday season deals. It mailed before the deals went live, giving members approximately ten days to review the full promotional lineup before the first purchase opportunity.

Wave 1 launched October 30 and ran through November 15. This is the most strategically valuable phase of the entire event — the deals are identical to what will be available on Black Friday itself, but the inventory is at its fullest, the crowds are minimal, and the selection within each promoted category is comprehensive.

Wave 2 launched November 14 and continued through December 1, covering the Thanksgiving and Black Friday weekend as well as Cyber Monday.

The implication of the wave structure: a member who shops Wave 1 on a Tuesday or Wednesday in early November experiences zero Black Friday crowd dynamics while capturing every available Black Friday discount. The deals do not improve after October 30 — they are the same deals. What changes is the inventory level and the shopping environment.

The Holiday Savings Book: The October Arrival Most Members Miss

The Costco Holiday Savings Book is the commercial intelligence document that enables the early-shopping strategy — and the document that most members discover only after the Wave 1 window has opened, because they were not expecting it in mid-October.

The Holiday Savings Book is separate from the regular monthly Member Savings coupon book. It arrives in mailboxes during approximately the third week of October — several weeks before the promotional window opens. This advance distribution is deliberate: it gives members time to review the full catalog, identify the specific items they want, confirm product specifications, compare against competing retailer offers, and plan their purchase timing before the wave launches.

For members who do not receive the physical book by mail (address not current, opted into digital-only communications), the digital equivalent is available on Costco.com and in the Costco app from the moment the mailing goes out. The app's Member Savings section and the Costco.com promotions page both host the Holiday Savings Book content in browsable digital format.

The most effective use of the Holiday Savings Book: review it item by item on arrival in mid-October, create a prioritized list of the specific deals relevant to your shopping needs, and set a calendar reminder for the Wave 1 launch date. When Wave 1 opens, go immediately — not eventually.

The Deal Categories: What Goes on Sale and By How Much

The Costco Black Friday event delivers its most significant discounts in specific categories that are consistent from year to year.

Understanding which categories generate the deepest discounts allows members to plan their November and December major purchases around Costco's promotional calendar.

Televisions — the single strongest Black Friday category

January and November are the best times to buy televisions at Costco, with savings of 20 to 50 percent off. Costco's TV pricing is already among the most competitive available to any consumer through any retail channel — and Black Friday creates an additional markdown layer on top of an already-low starting price. Large-screen LG, Samsung, and Sony OLED and QLED televisions receive the most significant Black Friday markdowns at Costco, with prices that frequently undercut Best Buy, Walmart, and Amazon's concurrent Black Friday TV deals.

The free Concierge Services warranty extension that applies to all Costco electronics purchases — adding one to two years of coverage beyond the manufacturer warranty — applies fully during Black Friday purchases. A television purchased at Costco's Black Friday pricing includes the same warranty extension that applies to any Costco electronics purchase at any time of year. This extended warranty, combined with the Black Friday markdown, is a total value package that most competing Black Friday TV deals cannot match.

Laptops and computing

Laptop deals appear consistently in Costco's Black Friday event — with Apple MacBook Air and MacBook Pro, Windows laptops from HP, Dell, and Lenovo, and premium tablet configurations receiving meaningful promotional markdowns. The 2025 event included $200 off the 15-inch MacBook Air as a pre-Black Friday electronics deal running through November 19. Similar deals are anticipated for 2026's electronics promotional cycle.

The laptop purchase quantity limit — typically two per member on promotional pricing — applies to Black Friday deals as it does to regular promotional electronics. Members who want to purchase multiple units for gift-giving should plan accordingly.

Major appliances — up to $700 off

Major appliance deals appear in both the Memorial Day sale and the Black Friday event at Costco — with the Black Friday appliance offers concentrating on refrigerators, washing machines, dryers, dishwashers, and ranges from brands including LG and Samsung.

Savings of up to $700 off on qualifying appliance purchases, combined with the Costco Concierge Services extended warranty, make November one of the two optimal months for appliance purchasing alongside Memorial Day.

Members planning a kitchen renovation or appliance replacement should specifically evaluate both the Memorial Day and Black Friday promotional windows before making a purchase — the pricing between the two events is comparable, and selecting based on specific model availability in each promotional cycle is the most effective approach.

Electronics accessories and audio

Premium wireless headphones, Bluetooth speakers, and home audio equipment receive Black Friday markdowns at Costco. Historical Black Friday deals have included $120 off Bose QuietComfort noise-canceling headphones (from $299.99 to $179.99), JBL waterproof speaker promotions, and significant markdowns on home theater sound systems.

Jewelry

Jewelry is one of the less-publicized but commercially significant Black Friday categories at Costco — with diamond jewelry, gold and silver pieces, and name-brand watches receiving meaningful holiday season markdowns. Costco's jewelry pricing is already substantially below comparable items at traditional jewelry retailers, and Black Friday creates an additional promotional layer on an already-competitive base price.

Toys and games

The toy section receives significant Black Friday attention — LEGO sets, board games, action figures, and popular toy brands at promotional pricing that positions Costco as a genuine Christmas gift shopping destination. LEGO sets at Costco, already available at prices below many specialty toy retailers, receive additional Black Friday markdowns that make the warehouse one of the most cost-effective sources for popular LEGO configurations during the holiday season.

Holiday food and seasonal items

Holiday food deals appear throughout November — premium imported cheeses, specialty charcuterie, holiday baking supplies, and the seasonal prepared foods that make Costco the go-to source for holiday entertaining. These food deals are not specifically labeled Black Friday but represent the same seasonal promotional pricing that accompanies the November promotional calendar.

Thanksgiving Day: The Warehouse Is Closed

Costco is closed on Thanksgiving Day. This is a consistent policy — one of a small number of national holidays when all Costco warehouses are shut.

For members planning Black Friday shopping at Costco, the Thanksgiving Day closure means that November shopping must happen either before Thanksgiving (during the Wave 1 window) or on Black Friday itself (the Friday after Thanksgiving, when warehouses open at standard morning hours, typically 9 or 10 a.m. depending on location).

The Thanksgiving Day closure creates a specific and commercially meaningful bifurcation: members who want to avoid Black Friday weekend crowds must complete their Costco holiday shopping in the Wave 1 window (late October through mid-November). Members who wait until Thanksgiving week find themselves facing either the closed-on-Thanksgiving limitation or the full Black Friday crowd experience when the warehouse reopens.

The online exception: While warehouses are closed on Thanksgiving, Costco.com operates online on Thanksgiving Day — with online-only Thanksgiving deals that are separate from the in-warehouse promotional pricing. Members who are comfortable shopping online can access specific Thanksgiving Day online offers that are not available at the warehouse, though the in-warehouse experience is unavailable on that specific day.

Cyber Monday: The Online-Only Finale

Cyber Monday — the Monday after Black Friday, in 2026 falling on December 1 — delivers Costco's online-exclusive promotional offers: specific electronics, appliances, and merchandise available only through Costco.com on that date, with one-day limited-time pricing.

The Cyber Monday online event at Costco includes the complete range of Costco.com's inventory — including items not available in every physical warehouse location — at pricing that may differ from or match the in-warehouse Black Friday event. For members who could not get to a warehouse during the Wave 1 or Black Friday weekend windows, Cyber Monday provides a final opportunity to capture holiday promotional pricing on online-eligible merchandise.

Members buying appliances during the Cyber Monday event should note the Costco Direct buy-more-save-more structure that applies online — purchasing multiple qualifying appliances simultaneously on Costco.com during promotional periods can unlock additional savings stacked on top of the individual item discount.

The Items That Sell Out First: What to Buy in Wave 1

Based on the consistent pattern of Costco Black Friday inventory depletion across multiple years, specific item categories sell through most quickly in Wave 1 and are frequently depleted or significantly reduced in selection by Black Friday weekend:

Premium televisions in the most popular size configurations — 65-inch and 75-inch OLED and QLED models from LG and Samsung.

The most popular screen sizes in the most popular picture quality tiers are the first to sell out in any electronic promotional event at Costco. Members who want a specific TV configuration should buy in Wave 1 and not assume it will be available on Black Friday.

The NuFACE and premium skincare devices that appear in the Holiday Savings Book — similar to the beauty section rotation discussed in the skincare guide, the premium device deals in the Holiday Savings Book sell out before Black Friday weekend at many locations.

LEGO sets in the most popular themes and configurations — the licensed LEGO sets (Star Wars, Harry Potter, Technic flagship sets) that receive Black Friday pricing at Costco are purchased quickly by gift planners who arrive in Wave 1.

Jewelry at promotional pricing — the most popular Holiday Savings Book jewelry deals sell through at a rate that reduces selection significantly by the traditional Black Friday weekend.

The Complete Strategy: How to Capture Every Available Costco Black Friday Saving

Experienced Costco Black Friday shoppers follow a consistent strategy that maximizes savings, eliminates crowd risk, and ensures access to full inventory selection:

Step one — locate the Holiday Savings Book in mid-October. Watch for it in the physical mailbox during the week of October 19, or access it digitally through the Costco app or Costco.com the moment it becomes available. Review it in full, create a prioritized list, and identify the specific items you want.

Step two — shop Wave 1 immediately, not eventually. The Wave 1 window opens October 30 and runs through mid-November. The first week of Wave 1 — ideally on a Tuesday or Wednesday — is the optimal shopping moment: full inventory, no crowds, full selection within each promoted category.

Step three — use the price adjustment window for items purchased before Wave 1. Any item purchased within 30 days before the Wave 1 promotional pricing becomes active is eligible for a price adjustment if the same item appears in the Holiday Savings Book at a lower price.

Check recent purchases against the Holiday Savings Book on October 30 and file price adjustment claims at membership services or online for any qualifying items.

Step four — monitor Costco.com for online-exclusive items during Wave 1. Some Holiday Savings Book promotions are available online only or in configurations that differ from the in-warehouse offering.

The JULYAPPLIANCES-style promotional codes that Costco uses for online appliance events may appear in the holiday season as well — check Costco.com's promotional section alongside the warehouse visit.

Step five — use the Costco Anywhere Visa for every purchase. The 2 percent cash back on all Costco purchases and the 3 percent reward structure on applicable categories applies fully to Black Friday purchases — stacking the holiday promotional discount on top of the ongoing card reward.

Step six — know the return policy before buying electronics.

Electronics and major appliances purchased at Costco have a 90-day return window — meaning items purchased in late October during Wave 1 have return eligibility through late January, comfortably covering the post-holiday period when gift assessments are made.
