Heads up, grocery shoppers: Walmart and Kroger are swapping out old-school paper price tags for digital ones that can change in real time. While stores say it’s to save time and cut down on paper waste, shoppers are worried this means prices could sneak up without warning—think Uber surge pricing, but for your cereal. If you want to avoid surprise price hikes, keep an eye on those digital tags and consider shopping local for more predictable deals. #Business #LocalBusiness #GroceryShopping
