In South Korea, Tesco and Samsung got together and created a brand called Home Plus. They put up these huge billboards in subway stations and other places. You peruse the aisles, find what you like, scan the QR code with your smartphone and place your order. Your shopping is delivered home. And the best part, you do all this while waiting for your chariot to arrive.
So what do you think - genius or not?
PS: They have 113 stores already... so obviously the Koreans do like it!
