Costco Black Friday 2025: Ads, Dates, and Shopping Tips

Store Hacks

November is always jam-packed with Costco Black Friday deals both in store and online, with the first wave of Costco's Black Friday deals predicted to arrive by Oct. 31, 2025. We won't likely see a Costco Holiday Savings book arrive in the mail until mid-October 2025, but in the meantime, we've compiled our best tips for shopping their sale.

Just keep in mind that Costco's Black Friday deals are different than the deals in the November Costco Coupon Book, and there are multiple waves of Black Friday deals that roll out every November.

Costco Black Friday is a monthlong sale with online and in-store deals in every category.

During Costco's Black Friday sale — which is a full month long — you'll see deals throughout the entire store and online. There's also an online-only sale on Thanksgiving Day and select online-only deals during their Cyber Monday Sale. We'll also see up to 40% off electronics and 20% - 30% off home items.

KCL predicts the next Costco Black Friday sale will go live on Oct. 31, 2025, with additional deals dropping Nov. 17, Nov. 28, and Dec. 1.

Costco hasn't announced the dates for their 2025 Black Friday Sale yet, but we expect they'll continue with multiple waves of deals, like they've done in previous years.

Here's how we predict the sale will go in 2025:

Oct. 31 - Nov. 16 (predicted): First wave of Black Friday deals
Nov. 17 - Dec. 1 (predicted): Second wave of Black Friday deals
Nov. 27 (predicted): Online-only Thanksgiving Day deals
Nov. 28 - Dec. 1 (predicted): Third wave of Black Friday deals
Dec. 1 (predicted): Online-only Cyber Monday deals

Online deals typically land 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 will open an hour earlier than normal, starting at 9 a.m. local time.

How do we make our prediction?

We base our predictions on the past four years of early Black Friday deals. Here's when their Black Friday sale began in prior years:

Friday, Nov. 1, 2024
Monday, Oct. 30, 2023
Monday, Oct. 31, 2022
Friday, Nov. 1, 2021

The Costco Black Friday Sale always overlaps with their 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.

Think of the Holiday Savings Book as the Costco Black Friday ad that's like a mega version of the Costco Coupon Book.

Here are our best predictions as to the timing of the 2025 coupon and savings book validity dates:

Oct. 22 - Nov. 16 (predicted): Costco November 2025 Coupon Book
Oct. 31 - Dec. 1 (predicted): Costco Holiday Savings Book with Black Friday deals
Nov. 19 - Dec. 24 (predicted): Costco December 2024 Coupon Book

Expect the Costco Black Friday ad (aka the Holiday Savings Book) to drop around Friday, Oct. 17.

Last year’s Costco Black Friday ad dropped on Oct. 18, 2024 — the second-to-last Friday in October and two weeks before the start of the sale. We predict they'll follow the same pattern next year, with the 2025 Holiday Savings Book arriving in mailboxes around Friday, Oct. 17, 2025.

There are no doorbusters or in-store-only deals in the Costco Black Friday sale, but there are some online-only deals.

The majority of the Costco Black Friday deals are available both online and in stores. But for the past few years, new deals are released on Thanksgiving Day and Cyber Monday and are available online only.

You can shop Costco Black Friday deals online if you're not a member, but you'll pay 5% more.

While you can technically shop Costco deals on its website as a non-member, you’ll have to pay a 5% surcharge on the items you purchase with Costco online shopping. If a Black Friday and Cyber Monday sale price is low enough, it might be worth it, but make sure you factor in that extra 5%.

The Costco return policy is literally forever, so your purchases are protected.

As you'll read in our guide to the Costco return policy, they offer a generous satisfaction guarantee. You can return most items at any time, even after years of ownership, for a full refund back to the original form of payment. This applies to both membership purchases and purchases made with a Costco Shop Card.

New deals arrive on Cyber Monday, but prices aren't any better.

If you see a low price during early waves of the Costco Black Friday sale, you'll want to jump on the deal. We don't see Costco dropping prices on the same items throughout the sale. They do add new items to the sale, but you won't see prices getting any lower if you wait.

Costco won't give price adjustments on Black Friday items — and they never price match competitors.

I chatted with a store employee and confirmed that Costco excludes their Black Friday pricing from their price adjustment policy. So don't expect to buy something at full price, then get refunded the difference if it goes on sale for Black Friday at Costco.

And Costco never price matches competitors; they'll only adjust to a lower price in their own sales, and you'll have 30 days to request the adjustment.

Costco doesn't offer rain checks for Black Friday deals.

You can't ask for a rain check if an on-sale item you want sells out before you can buy it. Costco’s Savings books’ fine print states “as supplies last.”
