Hate shopping for groceries? You'll like this year's Grand Prix winner in the Media Lions contest at Cannes.

     Cheil Worldwide in South Korea took home the coveted prize for creating a virtual grocery store in a Seoul subway for Tesco (the British chain that's been renamed Homeplus in Korea). The shelves are laid out just like a physical store, and the items are fully shoppable via smartphones and QR codes. People waiting for their trains can scan items right into an online cart, with the items to be delivered to their homes. A case-study video is here.
