Walmart's US e-commerce sales up 43% in Q4, thanks to growing online grocery business

Most notably, Walmart attributed the strong e-commerce growth to the expansion of its grocery pickup and delivery businesses, and a broader assortment on Walmart.com. The company has been challenging Amazon, Instacart, Target's Shipt and others on grocery. With grocery pickup, Walmart offers an alternative to the higher cost of using grocery delivery services, while still allowing for convenience, as its customers can skip shopping the aisles and instead remain in their cars while groceries are loaded into the trunk.
