The app guides you to a choice of locations in each city, where Mr Porter shopping bags will appear and a winner is chosen at random . You could win Lanvin sneakers, Paul Smith cufflinks or a pair of A.P.C. jeans. There are runner up prizes too. Give it a go, it sounds cool, it looks cool, so it’s probably pretty cool.
