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.
Instacart SameDay buyers who already use delivery, because the coupon is listed in the booklet and should apply on that service.
It can be combined with a $10 Chase United monthly Instacart credit, a $10 executive credit, and a $2 scheduling discount for up to $22 off total. The practical limit is that Costco SameDay prices are marked up versus warehouse pricing, so the savings may be partly offset.
Yes, it is meant for Costco SameDay/Instacart orders, but it may be targeted and not work for every account. The coupon is also noted as being in the booklet, so the valid dates matter.
Yes. Costco SameDay and Instacart pricing is marked up above warehouse prices, and long-distance orders can add a $10 fee, so the coupon may not fully offset the higher base cost.
The coupon can apply in the cart and still show no visible discount, then later reject a second attempt as already redeemed. That makes the promo feel janky, so it is worth checking the final checkout total before placing the order.
Food court menu items are reportedly not available for SameDay delivery, and frozen items may sit in a hot trunk during multi-stop delivery. That makes food safety and item availability important limits to consider before ordering.
Who's "we"? I didn't.
Given that I need a Costco subscription and $35 order minimum, I don't expect to tip at all.
If I use the instacart app, now that's a different story.
Your subscription and order $ doesnt change the fact someone is delivering it to you.

I don't tip for amazon, walmart, target, etc
Edit: Just found out that Amazon Fresh also charges a tip, so I guess this is common for instant deliveries. My bad.
Still would prefer if they just charged a delivery/service fee so I wouldn't need to think about what a fair tip amount would be.

Costco elevates online pricing. Then Instacart elevates online pricing some more. Then you have to tip for the pleasure of paying 2x elevated pricing after you already paid them $60-$130 to shop there in the first place. As much as Sams/Walmart sucks with delivery, at least the price is the same in the store, online, or if some spark delivery crackhead touches it. $10 is gone with 2 items in the cart compared to the warehouse price.
