Purchasing items on Costco.com for delivery, at least in the Bay Area, incurs a premium of about 20% on many (all?) items. This is to ensure the Instacart delivery people are paid fairly. On top of that there's the tipping that is always implied for service work. So it's not incredibly cheap in SF. It's cheaper for me to go there and take a Lyft home if I spend more than $100. Regardless I agree with your hope that retail looks more like Costco than Amazon.
