Costco's Memorial Day Sale is an annual 3-week sale with additional savings on select items.
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.

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.
