In-store 'Sat-nav' up and working now in a Tesco branch
We now have a comprehensive ‘sat-nav’ system working INSIDE one of our Tesco stores! The new service is able to show you where all your wanted products are on a store map, show you where you are on that map, and guide you round the store to pick up your products using the shortest route.
