Costco August 2026 Coupon Book: The Deals Worth Grabbing
The August 2026 coupon book is here, and it runs from Monday, July 27 through Sunday, August 23. This one has serious back-to-school energy – lunchbox snacks everywhere, kids apparel, and enough oral care deals to make your dentist weirdly proud of you.
As always, our friends over at Costco Insider have the entire book scanned page by page. Head over there to flip through all 20 pages. Below are the deals we think are actually worth your time.👇👇
Oral-B iO Complete Clean Electric Toothbrush 2 pk – $30 Off
The big-ticket deal of the month. Two rechargeable iO brushes in one box, which means you and your spouse can finally stop passing judgment on each other’s brush heads. Item 3907391, limit 3.
Kirkland Signature Organic Peanut Butter 2/28 oz – $9.99
Two big jars of organic peanut butter for under ten bucks, right as lunchbox season kicks off. No added sugar, two ingredients, made with US Valencia peanuts. The timing here is not a coincidence and we respect it. Item 555000, no limit.
The 1980s called and they want their track suits back. Too bad – at $14.99 for the jacket or pants after $5 off, we’re keeping them. Youth sizes are $12.99, so you can match with your kids whether they like it or not. There’s even a 6 pack of quarter socks for $9.99 to complete the look.
ReadyWise Emergency Food Supply Bucket – $79.99 After $30 Off
One for the preppers. 150 servings of shelf-stable food in a 14 lb bucket for $79.99. Whether you’re prepping for an actual emergency or just a week when nobody feels like cooking, this is solid insurance for about 53 cents a serving. Item 1628940, no limit, online.
Shark Stratos Cordless Vacuum – $239.99 After $60 Off
The Stratos with Clean Sense IQ and the DuoClean PowerFins HairPro head, which is a lot of words that mean it will not get choked out by pet hair. Sixty bucks off makes this one of the better cordless vacuum deals we’ve seen this year. Item 7750815, limit 5.
Kirkland Signature Organic K-Cup Pods 120 ct – $8 Off
All four roasts are included – Pacific Bold, Breakfast Blend, Summit Roast, and French Roast. 120 pods per box, $8 off, limit 5. If your household burns through K-Cups like ours does, this is a stock-up moment.
Huggies Plus Diapers – $10 Off
Sizes 1 through 7, ten bucks off per box, limit 3 per size. Pampers Swaddlers are also $10 off if your baby has brand opinions. Kirkland Baby Wipes are $4 off too, because Costco knows exactly who is walking through that door in August.
Welch’s Fruit Snacks 90 ct – $3.80 Off
Ninety pouches. That’s a full school semester of lunchbox filler, or three weeks if your kids find the box. Item 1374492, limit 4.
