Customers can do most of their Walmart shopping online. The company has an online store with products in all departments, including groceries, that are available for delivery.
Online shopping through Walmart's website is limited to products that are available through the website. More selections are available in departments like household goods, but there are many bulk food items available for purchase.
As of 2015, Walmart is also trying out a grocery delivery service limited to certain areas of the country. This service allows customers to order items found in their local Walmart stores and have their groceries delivered the same day. Delivery is limited to certain hours and a delivery fee is added to the grocery cost.
