The difference here is that shoppers in that store can see the final price and actual savings before purchasing. Can you do the same with Instacart?

> Can you do the same with Instacart?

Instacart shows you the final price. The price they paid for the goods is immaterial - you're choosing the convenience of not having to write your own delivery app, recruiting employees, or set up payment.

When you walk into a book store, do you demand to see the book price broken down into manufacturer's price, store rent, employee pay, and store profit and complain when the difference between the manufacturer's price and the retail price is too high?
