The future shopscape will be emptier, but more attractive. Shoppers can expect new rewards for simply showing up. Shopkick, a mobile-phone app, gives American shoppers points that earn them goodies like iTunes songs just for stepping across the threshold of a participating store. Inspired by Apple, shops promise “experience” and hope that sales will follow. Germany’s Kochhaus claims to be the first food store organised around recipes rather than grocery categories. The ingredients are strewn across tables, not stacked on shelves. Some shops will opt to sell nothing at all on the premises. Desigual, a Spanish fashion merchant, has shops in Barcelona and Paris that carry only samples. Shoppers are helped to assemble them into outfits that they then buy online.
