Costco September 2026 Coupon Book: The P&G Shop Card Deal Is Back
No breather this time. The September 2026 coupon book runs from Monday, August 24 through Sunday, September 20, which means it picks up the morning after the August book wraps. The usual gap week just did not happen this round.
One date to circle: Costco is closed Monday, September 7 for Labor Day. Plan the hot dog run accordingly.
The headliner is the return of the P&G Buy More, Save More promotion. Spend $100 on eligible P&G products and you get a $25 Costco Shop Card. Spend $200 and it jumps to $60. Over 70 items qualify, the limit is two Shop Cards per membership, and you can stack it across multiple trips through September 20. Look for the “Save More” stamp to spot what counts.
Beyond that, this book leans hard into fall. Flannel and fleece are back, Halloween candy is creeping in, cold and flu season gets the full DayQuil treatment, and the pharmacy is advertising flu shots at no cost on most insurance plans.
As always, our friends over at Costco Insider have the entire book scanned page by page. Head over there to flip through all 21 pages. Below are the deals we think are actually worth your time.👇👇
P&G Buy More, Save More – Up to $60 in Costco Shop Cards
The one to build your trip around. Spend $100 on eligible P&G products for a $25 Shop Card, or $200 for $60. Submit your receipts at GetPGOffer.com and the card follows. Over 70 qualifying items across Tide, Bounty, Charmin, Dawn, Olay, Gillette, and more, so if you were already due for a household restock, the $200 tier is easier to hit than it sounds. Limit 2 Shop Cards per membership number.
Dyson V10 Konical Cordless Stick Vacuum with Car Cleaning Kit – $100 Off
The best straight discount in the book. A hundred bucks off a Dyson cordless, and the car cleaning kit is bundled in, which is the attachment set you always mean to buy separately and never do. Item 6264351, limit 5, online.
Philips Sonicare DiamondClean Rechargeable Toothbrush 2 pk – $179.99 After $100 Off
Two DiamondClean brushes for $179.99. That is the top of the Sonicare line, and buying the pair means nobody in the house has to negotiate over whose turn it is on the charger. Item 5239377, limit 5. If that is more toothbrush than you need, the Advanced Clean 2 pack is $69.99 after $30 off.
Michelin Tires – $80 Off Any Set of 4
Eighty dollars off any set of four Michelins, installation included, no limit. Tire coupons show up often enough that it is easy to shrug at them, but this one has no item restrictions at all. If your tread is getting thin heading into wet season, this is your window.
Osaki A.I. Vera 3D Massage Chair – $2,999.99 After $1,500 Off
Fifteen hundred dollars off is the largest single discount in the book. It is still a three thousand dollar chair, so this is either an absurd luxury or the best purchase you make all year, and we suspect your lower back already knows which. Limit 5.
Mars Chocolate Candy Variety Pack 30 ct – $7.50 Off
Thirty full size bars. Halloween is still weeks away, which is exactly the problem, because a box this size does not survive September in most households. Buy it now at $7.50 off, hide it better than you did last year. Item 705876, limit 4.
Vital Proteins Collagen Peptides 24 oz – $23.99 After $6 Off
The unflavored 24 oz tub, which is the one that actually disappears into coffee without announcing itself. Under twenty four dollars is a good price for this size. Item 1303463, limit 3.
Dino Buddies Chicken Breast Nuggets 5 lbs – $10.99 After $4 Off
Five pounds of dinosaur shaped chicken for under eleven dollars. School lunch season is here and there is no negotiating with a kid who has decided the stegosaurus tastes better than the triceratops. Item 1560758, no limit.

One More Thing
Costco Pharmacy is advertising flu shots on the back page, at no cost on most insurance plans. Walk-ins are welcome, or you can book online at Costco.com. If you are already making a trip for the P&G stock-up, you may as well knock that out in the same visit and save yourself a September errand.
That’s our take on September. Hit the full book at Costco Insider for every last deal, and if you spot something great in your warehouse that we missed, drop it in the comments.
