When things get busy for one family, they depend on Google Express and Walmart to help them maintain their shopping list. Various household staples are added: French roast coffee pods, laundry detergent and paper towels. When everyone is baking cookies, they are able to order a baking pan. And when the family dog deflates their football, a new one is added, too. Walmart offers special discounts on orders placed using Google Express on Google Home devices for a limited time.
