When Costco Has Sales: Savings Periods, Black Friday
Costco runs dated Warehouse Savings periods all year, and its 2026 Holiday Savings come in waves from October 30 to November 30.
On this page

Store policies change. This is a summary in our own words of Costco's Warehouse Savings, Holiday Savings and Black Friday pages, read on October 26, 2026. Dates and prices on those pages are the ones that apply.
Warehouse Savings: dated periods
Costco's recurring sale is Warehouse Savings, a list of instant markdowns on its site. Each list carries a validity window. The list live on October 26, 2026 runs from October 19 to November 15, 2026.
What the page shows for each deal:
- The item and its item number
- The amount off, shown as "After $X OFF"
- A purchase limit, such as 5 or 10
- Whether it is in the warehouse, online or both
Costco notes that the listed prices are warehouse prices, and that prices can differ in Alaska, Hawaii, Puerto Rico, Costco Business Centers and online. Many items also say selection varies by location, so a deal on the page is not a promise that your warehouse stocks it.
The 2026 Holiday Savings calendar
Costco's Holiday Savings page sets out the holiday season in dated waves:
| Window | What Costco lists |
|---|---|
| October 30 to November 15 | First wave of holiday savings |
| November 16 to November 30 | Second wave |
| November 26 | Thanksgiving: Costco says it will be closed |
| November 27 to November 30 | Deals valid for these four days |
| November 30 | Deals valid on this day only |
Costco says valid dates vary by item, so check the dates shown on each deal, and that offers last while supplies last. Some items on the page were already marked valid from October 23.
Costco Black Friday
Costco's Black Friday page for 2026 shows a preview with "new savings coming soon". It points members to the email offers list for early news and to the warehouse locator to check Black Friday hours at each store. It also highlights the While Supplies Last section for price reductions outside the big events, and Treasure Hunt and What's New for rotating items.
Buy before a sale? Know the price adjustment rule
Costco will refund a price drop on its own items within 30 days of purchase. For an item on a dated promotion, the request must also be made while that promotion is still running. So if you bought something on October 25 and it shows up in the October 30 wave, ask during the wave, not after November 15. See our Costco price adjustment summary for the steps.
How to track Costco sales
- Open the Warehouse Savings page at the start of each period and note the end date.
- Check the Holiday Savings page again on November 16 and November 27, when new windows open.
- Keep receipts for big purchases in the 30 days before a sale.
- Watch purchase limits: the page states them per item.
