Smart, observant, and hugely entertaining, Why We Buy--For the Internet Age is based on hard data gleaned from thousands of hours of field research conducted by Underhill's firm, Envirosell—on the Internet as well as in shopping malls, department stores, and supermarkets across America and around the world. He demonstrates vividly what U.S. retailers can learn from their global counterparts, and why the vast majority of growth will occur where "money is young" in the new markets—Dublin, Moscow, Dubai among others. With his team of sleuths tracking our every move, from sweater displays at the mall to the beverage cooler at the drugstore to the I-Tunes homepage, Underhill describes the complex interactions between merchants, marketers, and increasingly knowledgeable and cosmopolitan consumers. New material includes: * The latest trends in online retail—what retailers are doing right and what they're doing wrong—and how nearly every Internet retailer from I-Tunes to Amazon can drastically improve how it serves its customers. *A guided tour of the most innovative stores, malls and retail environments around the world—almost all of which are springing up in countries where prosperity is new. An enormous indoor ski slope attracts shoppers to a mall in Dubai; an uber luxurious Sao Paolo department store provides personal shoppers; a mall in South Africa has a wave pool for surfing. The new Why We Buy is an essential guide to how to entice the changing customers and the eager consumers of the twenty-first century.
