That difference brings its own questions. When do the deals actually start? Are online and warehouse prices the same? Is a membership worth paying for just to shop the holiday sales? And how do Costco's prices compare once warranties and delivery are included?
This guide explains how Costco's 2026 holiday savings event is structured, the dollar savings shoppers have commonly seen in key categories, and how to decide whether Costco is the right place for your holiday purchases. All figures are approximate and should be confirmed with Costco before buying.
How Costco's 2026 Holiday Savings Event Works
Costco does not run a single Black Friday doorbuster day. Its 2026 holiday savings event runs from October 30 through November 30 in overlapping waves, and each item in the ad carries its own valid dates.
Sale window | 2026 dates | Where |
|---|---|---|
Wave one | Oct. 30 to Nov. 15 | Warehouse and online |
Wave two (largest) | Nov. 16 to Nov. 30 | Warehouse and online |
Thanksgiving Day deals | Nov. 26 | Online only (warehouses closed) |
Black Friday weekend | Nov. 27 to Nov. 30 | Warehouse and online |
Cyber Monday deals | Nov. 30 | Online only |
A few practical points follow from this structure. First, the date printed next to an item is the one that matters; a deal you saw in the ad may not be live yet. Second, warehouse and Costco.com prices can differ, and some online items add shipping and handling. Third, many listings carry purchase limits per household, ranging from a couple of units on laptops to more on TVs. Finally, Costco's price adjustment policy has generally covered price drops within 30 days of purchase, which can help if you buy before an item's sale window opens. Confirm current terms before relying on it.
Tech Deals: TVs, Computers, and Smart Home
TVs make up a large share of Costco's 2026 holiday ad, and most include a bundled coverage plan that extends total protection to five years. Examples of advertised prices include:
Product type | Advertised 2026 price | Sale window |
|---|---|---|
43-inch 4K TV | $199.99 | Varies by listing |
55-inch mini-LED 4K TV | $299.99 | Varies by listing |
65-inch mini-LED 4K TV | $499.99 to $529.99 | Nov. 16 to 30 |
65-inch OLED TV | $999.99 | Varies by listing |
100-inch 4K TV | $999.99 | Nov. 27 to 30 |
27-inch high-refresh gaming monitor | $299.99 | Oct. 30 to Nov. 15 |
Laptops and desktops. Costco's ad lists many computers as dollar amounts off, with savings of up to $600 on select gaming laptops, and a Cyber Monday computer event advertising $100 to $600 off select models on November 30. Because final prices are not always shown in the ad, compare the configuration and total price on Costco.com once each deal goes live.
Smart home and security. Home security kits, outdoor camera bundles, and video doorbell packages appear in the $99.99 to $149.99 range, often bundled with extras such as chimes or batteries.
