Costco’s holiday savings run October 30 to November 30, but in separate windows with their own items. Every one of the 47 Costco deals we track from its printed book is in the first window, which ends November 15, so that sale is closing. The median discount on the 44 items that show a regular price is 23%, and 5 TVs give only a “from” price.
Last updated November 10, 2026. Windows are from Costco’s Holiday Savings page, opened that day. Prices are the advertised warehouse prices from our scan of the 29-page savings book, read November 3. Online prices can differ and a Costco membership is required.
| Window | What we know |
|---|---|
| Oct 30–Nov 15 | The first window. All 49 items we track from the printed book carry these dates (a few start earlier). |
| Nov 16–30 | Second window. Costco’s page lists it separately. |
| Nov 26 | Costco is closed for Thanksgiving. Online-only items are listed for this date. |
| Nov 27–30 | Black Friday weekend window. |
| Nov 30 | Cyber Monday items, online only. |
Costco’s terms say savings are not combinable with other savings, warehouse prices are shown, online may be higher, and items may have limits. Costco is closed on Thursday, November 26, 2026.
Where the book’s discounts are deepest
| Category | Items with a regular price | Median off | Deepest |

| Home & kitchen | 18 | 25% | 44% |
| Fashion | 9 | 20% | 25% |

Online-only items average a deeper cut than warehouse items – the 17 online-only items have a median discount of 29%, against 21% for the 27 warehouse items. Furniture, spas and a security system are among the online items with the biggest cuts, while the warehouse list is mostly small accessories and jewelry. If you plan to shop in person, the realistic expectation is closer to 21%.

The TVs have no “was” price
The book’s 5 TV listings show a “from” price or a single price but no regular price, so we cannot compute a percentage. Use our TV price check to compare against Samsung.com and Best Buy, and the TV deal list for current prices.
Price adjustment and returns at Costco
- Price adjustment. For Costco.com orders on promotional items, a request must be made within the active promotion dates and within 30 days of purchase. Costco does not match other retailers or compare Costco.com with warehouse prices. Warehouse requests go to the returns counter at the purchase location (Costco’s page). See also our price-match guide.
- Returns. No holiday extension. Costco refunds most items with no time limit, with a 90-day window from receipt for TVs, computers, tablets, smartwatches, cameras, drones and phones (Costco’s page). Our return windows guide compares it with other stores.
How to use this
Buy from the first-window list before November 15 if you want those items, since the book’s dates end then. For November 27 to 30 items, Costco’s page lists the Black Friday window but our scan has no prices for it yet. Check the ad status guide and the dates guide for updates, and browse the Costco store page. Sam’s Club’s November book is covered on its ad page.
Questions we get
Is Costco open on Black Friday? Costco’s page says it is closed Thursday, November 26. We could not find Black Friday hours on the pages we opened, so check your warehouse.
Do I need a membership for Costco’s Black Friday deals? Yes. Costco’s terms on the page require membership.
Are Costco’s online prices the same as the book? Not always. Costco says warehouse pricing is shown and online may be higher.
