Do your grocery shopping from the train station
grocery shop from the luxury of your own subway car
Talk about innovative... A grocery store chain (Tesco's Home Plus) in South Korea had the brilliant idea to take photos of the products on their shelves (with the bar codes showing), make life-size versions of them, and put the photos up in subway stations around Seoul so people could shop while waiting for the train on their daily commute.
Using the bar code scanner app on their smart phone (an app I adore, by the way) a person can take pictures of the bar codes for the items they want to buy, which then puts that item in their virtual cart. After using their phone again to check out, the groceries are delivered to their home at the end of the work day.
This campaign (which I wouldn't necessarily categorize as "advertising" as much as an innovative/interactive shopping application) won the Grand Prix award at the Cannes Lions Festival of Creativity - a very cool prize indeed.
