How to buy groceries online?

Google And Instacart offer the opportunity to shop for groceries online, from the comfort of your couch.
With traditional grocery stores offering a limited selection of products online, Google Shopping Express offers the solution to shop online from multiple stores, without the need to go to every website.

After purchasing the groceries your need, Instacart takes the groceries from the store to your house.
Instacart charges a fee for each delivery, starting as low as $2.99. For a membership fee, Instacart delivers all groceries to your house for free, and Google Shopping Express offers unlimited deliveries for a year with a $95 membership fee.
