Walmart’s investments in e-commerce, including online grocery delivery and pickup, are continuing to pay off for the retailer. In the company’s Q2 earnings, released this morning, Walmart reported its U.S. e-commerce sales were up 97% — an increase attributed to more customers shopping online during the pandemic, stocking up on household supplies, and shopping for grocery items online.

Today, Walmart offers grocery pickup at 3,450 locations and same-day delivery at 2,730 stores. Since February, it has expanded time slots by 30% to help meet consumer demand.
