If you've got a Costco membership, you're in for a treat around Memorial Day. Their sale kicks off in mid-May and lasts for around three weeks, ending the first weekend of June, with lots of savings on items like household appliances, backyard essentials, furniture, food, and BBQ supplies.
During the last go-around, we saw the biggest savings on appliances (up to 44% off for a Samsung bundle), but we also saw more than 20% off select groceries.
While Costco is not open on Memorial Day itself, their special Costco deals for Memorial Day will be available to shop online during the entire sale. We'll keep this post updated with the best Costco Memorial Day deals we're finding before and after the holiday.

Costco's Memorial Day Sale is an annual 3-week sale with additional savings on appliances, mattresses, food, and more.
Some of the deals featured for Memorial Day are different than the ones you see in the May edition of the Costco Coupon Book, as the Memorial Day sale includes additional savings on appliances, mattresses, and more.
Keep in mind that Costco stores are closed on Memorial Day itself, but you can still shop online during the entire 3-week sale (or in stores on the days they are open). Also remember that you'll only get the advertised prices if you're a Costco member.
KCL predicts the next Costco Memorial Day Sale will start on Thursday, May 14, 2026.
Costco hasn't officially announced the next date for their 2026 Memorial Day Sale, but based on what they've done in recent years, KCL predicts that the next sale will happen from Thursday, May 14, through Sunday, June 7, 2026. Look for an announcement on Costco.com or in the Costco app (download for iOS / Android) confirming that the Memorial Day Savings have started.
The initial round of deals is always for big-ticket items like appliances and mattresses, with additional deals rolling out in the week before Memorial Day (May 25, 2026). The appliance deals will likely end on June 7, but a Spend & Save promotion may end a few days prior (around June 3).
Is Costco open on Memorial Day?

Tips for Shopping the Costco Memorial Day Sale
To make the most of your Costco Memorial Day shopping experience, keep these tips in mind:
Shop online.
While Costco’s physical warehouse locations offer excellent deals, you can often find exclusive online-only discounts at Costco.com during the Costco Memorial Day Sale. Many of these items ship for free.
Use Costco's price adjustment policy to your advantage.
With the Costco Price Adjustment Policy, if you purchase an item from Costco and it goes on sale within 30 days, you can request a price adjustment to refund you the difference. This policy can help you save even more, no matter when you shop (before or after a sale).
Consider a membership.
Although Costco is a membership-based warehouse club, you can still shop during the Memorial Day Sale without a membership. However, as a non-member, you’ll pay a 5% surcharge on every purchase. Check out our Costco membership guide for help choosing the right level of membership.

In 2025, you could stack your savings with the Costco Direct promotion. With this promotion, the more you purchase from Costco Direct in one transaction, the more you save. Your items had to be shipped to the same address to receive these savings:
Buy 2 Items, Save $150
Buy 3 Items, Save $300
Buy 4 Items, Save $450
Buy 5 or more Items, Save $600
Costco also has a spend $1,999, save $300 or spend $2,499, save $500 promotion on select appliances during the Memorial Day event.
KCL TIP: If you see "Costco Direct" on an item listed on Costco.com, it just means the product will be shipped from a Costco distribution center instead of a Costco warehouse. This helps them speed up the delivery process, especially for large items.
