Editorial correction — October 13, 2026: The earlier version presented a four-wave 2026 sale schedule and strong savings claims without verified support. Those claims have been removed. This guide does not currently list verified 2026 Black Friday offers.
Black Friday falls on November 27, 2026, and Cyber Monday on November 30. Costco’s product promotions can have their own dates and conditions. Use the year and validity period printed on the offer itself; the general holiday calendar is not a retailer announcement.
A specific trap: a current-looking page with old offer dates
The Costco Holiday Savings page opened for this review contains offers explicitly dated November 28–December 1, 2025. Its presence online in 2026 does not make those prices or dates current. We have not relabeled that sale as a 2026 event.
When a search result looks promising, open it and inspect the small print next to the actual product. Check every item separately; one event page can contain several validity windows.
Use an item-by-item comparison
| Record | What to verify |
|---|---|
| Exact product and item number | Match specifications, size, model suffix and included accessories. |
| Offer year and valid dates | Confirm that the promotion covers the day you intend to buy. |
| Sales channel | Identify warehouse-only, online-only or both; do not assume the price transfers. |
| Location and membership | Check availability and eligibility for your warehouse, country and account. |
| Total cost | Include delivery, installation, removal, accessories and taxes where applicable. |
| Returns and adjustments | Read the current rules for that product and purchase channel. |
Set your budget before reading the catalogue
Make a short list of purchases you already need. Add the exact model or required features and a maximum total price. An attractive catalogue should not turn every discounted product into a new purchase.
For example, a hypothetical $900 appliance with $80 of necessary extras costs $980 before tax. A $950 alternative that includes those same extras may cost less. These are comparison examples, not Costco prices, installation promises or live offers.
Do not treat a return policy as price insurance
A lower price appearing later does not by itself establish an adjustment entitlement. Ask Costco’s customer service about the current eligibility, deadline and process for your specific purchase before relying on an adjustment. Warehouse and online procedures can differ. Keep the receipt and offer terms.
Check product-specific return exceptions and any requirements for electronics, appliances, customized goods or other restricted categories. A return window is not a reason to buy an item you are unlikely to keep.
Before travelling to a warehouse
Use Costco’s official warehouse information to confirm the selected location’s opening hours, including holiday changes. Do not infer special Black Friday hours from an earlier year. Online availability also does not prove a nearby warehouse has stock.
What is confirmed in this article?
The calendar dates and the year printed on the historical source above. We have not verified a 2026 Costco sale-wave schedule, individual Black Friday prices or stock availability. Keep this page as a comparison checklist and use current Costco offer terms for a purchase decision. Continue with the Black Friday 2026 guide.
