Grocery stores and supermarkets are combating inflation in part by offering more private-label goods. Many shoppers switched to house brands during pandemic shortages of name brands and stuck with them. For supermarkets, sales of store-brand products can be more profitable than sales of name-brand goods. Food stores are adding automation technology to cut costs, such as electronic price labels on shelves, cameras for measuring stock levels, and store-cleaning robots. They’re also automating picking goods at distribution centers to lower labor costs.
