The Walmart Grocery app is an easy way to have food and other consumer goods delivered to your door. You can also place an order for pickup at your local store. Here’s what you need to know about the app and how it works.

The Walmart Grocery app lets you shop online for food and household items from the giant retailer, then gives you the option to have them delivered to your home or pick them up. You pay the same price as you would in a physical store. Walmart promises there are no markups or hidden fees. If an item is out of stock, the store will replace it with a similar item (but only if you choose to replace it). It’s available on both iOS and Android.

There is no fee for curbside pickup, making it the cheaper option. Here’s how it works:

Open the app and log in to your account if necessary. Then select Pickup & delivery.
