Porteur is a new bicycle brand that has a one-for-one scheme, kind of like Tom's shoes. Buy a bike and they'll donate one. In order to promote their 10% sale, they decided to run the ad where cyclists were sure to see it: On the street. Made from water soluble paint, ads were made out of the road markings pointing out the bicycle lane. Clever use of a timely 10% discount. Because when the ads disappear so does the sale.
Fair enough. But what happens if it doesn't rain or snow in Stockholm for a bit? I realize this is impossible in spring there, but if we pretended climate change hit the land of Vikings, when's the official sale end?
