Found this little ditty at designview.com. Tesco installed large, wall-length billboards in Korean subway stations, designed to look like a series of supermarket shelves
and displaying images and prices of a range of common products. Users scan the bar-code of any product they would like to purchase with their smart phones. After the web transaction is completed, the products are delivered to the user’s home within the day.
I’m not sure how I feel about ordering my groceries from a place that usually smells like a wet petting zoo and stale urine… sort of the opposite of going to the supermarket when you’re starving.
