Between returning from vacation and being completely swamped with work, I’d been in need of a Costco run. I was considering doing a Costco SameDay order (aka “InstaCart”), but in the penultimate stage of the cart, the $3 “priority fee” annoyed me enough to hesitate. I was distracted the rest of the day with work phone calls. By the next morning, I realized I needed gas anyway, so I just went when they opened and avoided the crowds.

Comparing the receipt of what I purchased to what the InstaCart was sobering. Individual items were an average of 9.3% above Warehouse prices. With the additional fees, InstaCart was 18% more expensive. Adding a driver tip, almost 29% more expensive. So, InstaCart is not practical for a medium-sized Costco purchase. Also, they lack several of Costco deli/ready-to-eat options (like Nigiri).

InstaCart versus in-warehouse Costco

Notes: (1)The $1 difference in coupons was a poorly-worded promotion for an additional $1 off 2 packages of cereal. (2) InstaCart+ membership offers a discount of $8.93 on the service fee. The membership includes free PeacockTV (for EuroVision!) and 1 year of NY Times Cooking. There is a discount on the membership for Costco members. (3) The delivery fee of $5.99 is waived if you have InstaCart+
