Costco Black Friday: Ads, PREDICTED Dates, and Shopping Tips

Q: What KCL Experts Think You Should Know

Here's when to shop: The first wave of Costco Black Friday usually arrives online and in stores on the last Friday of October, with additional waves of deals dropping on the third Monday of November, Thanksgiving Day, Black Friday, and Cyber Monday. Here's when stores open: Online deals typically start at midnight on the start date, while in-store deals start when doors open: 10 a.m. local time. On Black Friday itself, Costco stores typically open an hour earlier than normal, starting at 9 a.m. local time. Use the KCL app: Download the free KCL app to set Deal Planner alerts so you never miss a price drop or hot deal. You MUST have a Costco membership: To shop in-store, you'll need a Costco membership (non-members can shop online, but they'll pay 5% more). Look for the Costco Black Friday ad (aka the Holiday Savings Book): It should arrive in your mailbox the week of Oct. 19, 2026. The Costco Black Friday Sale overlaps with the November and December Coupon Books: The Holiday Savings Book shouldn't be confused with the Costco Coupon Book. In fact, it's an entirely separate book that's nestled right in between the release of the November and December books. Costco's Black Friday sale is a full month long: You'll see deals throughout the entire store and online. Find online-only deals on two days: There's an online-only sale on Thanksgiving Day and select online-only deals during Cyber Monday. Expect big discounts on multiple products: We'll see up to 38% off furniture and 20% - 30% off home items.

Tips on How to Make Your Deal Shopping a Success

1. Shopping Options: Deals are available both online and in stores for most items. But new deals are released on Thanksgiving Day and Cyber Monday and are available online only.

2. Doorbusters: No doorbusters are offered.

3. Holiday Policies:

Rain Checks: Costco doesn't offer rain checks for Black Friday deals.
Price Adjustments: No Costco price adjustments on Black Friday items, and they never price match competitors.
Returns: The Costco return policy is literally forever, so your purchases are protected.

4. Membership Required: To shop in-store, you'll need a Costco membership (non-members can shop online, but they'll pay 5% more).

5. Cyber Monday Sale: It should be on Nov. 30 (predicted). New deals arrive on Cyber Monday, but Black Friday prices don't drop any lower.
