Costco Unadvertised Sales! AUGUST 2021

*UPDATE* 8/27/21.
It’s time for another edition of Costco unadvertised sales! Here are some of the unadvertised deals for the month of AUGUST 2021 being offered at select Costco locations, while supplies last. Some deals may be regional. I’ll update this post periodically with new sales.

I spotted these products at the Covington, Washington Costco (some were spotted at the Tukwila or Federal Way, WA locations). Some items may not be available or may not be on sale at all Costco locations. I wish Costco would just make all the sales national but sometimes they don’t. Prices may vary by location. Limited to stock on hand. When in doubt, call your local Costco before you go.

Click on ‘more info‘ to take you to the individual post that describes the product. Happy shopping!!

Products that are italicized are new on this list since the latest update.

YMMV on these Costco unadvertised sales. These products were originally spotted at the Covington, WA (and/or Federal Way, WA Costco and/or Tukwila, WA Costco) location but are not guaranteed to be in stock by the time you visit that Costco warehouse location.
Price and participation may vary so it may not be available at your local Costco or it may not be on sale at your local Costco or it may be a different price at your local Costco (especially in Alaska, Hawaii, and Puerto Rico).
Prices and sales dates may change at any time without notice.
Products may sell out before the end of the sale date and they might not get restocked.
This list does not represent everything that is on sale at Costco.

A lot of products at Costco are seasonal items and when they sell out, they are not restocked.
Some products are sold regionally and other products are sold nationally.
Some products sold nationally may not be on sale at all Costco locations.
Costco inventory changes constantly and I do not have access to that information.
Photos may not be a perfect representation of the product.
Color of the product in real life may vary from the photo.
Unadvertised sales or secret sales in this post are sales that are not included in the Savings Book (aka, the coupon book).
This is just a posting of a deal and not an endorsement or recommendation of any product or of Costco. Please do your own research before making any purchase.
Thanks for visiting my Costco blog!
