Costco Same-Day Delivery: $10 Off $25+ Orders
Costco has launched a new Same-Day Delivery promotion that lets members save $10 on qualifying delivery orders through August 23, 2026. There are two versions of the offer, one for regular Costco Same-Day orders and another for Costco Business Center Same-Day orders.
The standard Costco Same-Day promotion offers $10 off a $25 or more order when you use promo code SUMMERSAMEDAY26 at checkout.
If you’re ordering from a Costco Business Center, you can instead save $10 on a $35 or more order using promo code BDSUMMERSAMEDAY26.
Both offers are valid from July 27 through August 23, 2026, are limited to one redemption per membership, and are available in eligible delivery areas. Same-Day orders are fulfilled through Instacart, so prices may be higher than warehouse pricing.
