With the app called Instacart, you can now buy Groceries online and have them delivered at your door. 

It allows users to order groceries online or on their phones and have them delivered right to their front doorstep in as little as an hour. 

You select your city and store, add items to your cart, choose a delivery time and then check out, then the items are delivered to your home. 

You can sign up for an annual subscription, but other options are available.

The service is also now available in Potsdam, Canton, and Cortland.
