This Costco SameDay coupon is a small discount on Instacart delivered Costco orders, and it can stack with other credits like executive rewards or scheduling discounts. The main appeal is convenience, especially when the order qualifies and the coupon actually applies. The catch is that Costco and Instacart pricing is marked up versus warehouse prices, so the $10 can disappear quickly once delivery fees and tip are added. There are also reports of targeting, redemption glitches, and delivery range or food safety concerns, so it works best when the math still makes sense.
The coupon can work on Instacart SameDay orders when the booklet dates are followed.
Costco SameDay orders are shopped and delivered by Instacart, which supports using Instacart checkout.
The $10 off offer may stack with an Executive credit and a scheduling discount for larger total savings.
A Chase United monthly Instacart credit for a $150 order could add extra value alongside the Costco SameDay coupon.
The coupon may be targeted and can fail to apply during checkout.
The coupon experience can be janky, including cases where it applies without showing a discount or flags as already redeemed.
Instacart and Costco online pricing can be higher than local warehouse pricing, which can make the $10 off feel ineffective.
Frozen items may sit in a hot trunk for a couple hours during delivery, raising food-safety concerns.
