Update 9/25/26: Reposting since more people are getting the code to work now: try COSTCO26 or COSTCO20 for 20% off.
Update 9/24/26: 20% off with promo code COSTCO26.
DoorDash announced today that Costco is a new retailer available on their platform. You’ll be able to link your Costco membership in DoorDash to get member pricing.
They also released a promo code COSTCO20 to get 20% off a Costco order via DoorDash. Valid through 11/1/26. Max discount with this promo code is $50. (Update: code is not working for most people. YMMV.)
Our Verdict
Adding Costco is another big get for DoorDash. And the 20% code is a nice discount with a nice max discount of $50.
DoorDash already had tons of popular non-restaurant merchants like Aldi, Shoprite, Walgreen’s, Lowe’s, Home Depot, Staples, Target, BJ’s and tons more.
Of course, my mind goes immediately to the Chase credits: many Chase cards come with a quarterly or monthly $10 credit for non-restaurants, and these should now work for ordering Costco. The Sapphire Reserve comes with two $10 non-restaurant credit and one $15 anywhere credit which should now work for ordering Costco.
And so Costco is now available on: DoorDash, Instacart, and UberEATS. Just yesterday, UberEATS announced that Costco is available in 47 states (apparently they expanded their footprint of where they’ll do Costco deliveries).
