Use the Walmart app. Type in what you want. If it's in the store, it'll tell you the isle it's in. If not, you may be able to ship to store. Also, they have a new app that allows you to grocery shop online. You can pick up the food or have it delivered if you're in range.
You wont find it at the Northampton walmart. They have a limited stock of things due to it being a small store.
I've never even heard of that before. Sorry i couldn't be of much help
