Revolutionary retail guru Paco Underhill is back with a completely revised edition of his classic, witty bestselling book on our ever-evolving consumer culture -- full of fresh observations and important lessons from the cutting edge of retail, which is taking place in the world's emerging markets. 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 iTunes 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 its customers with personal shoppers; a mall in South Africa has a wave pool for surfing.

The new Why We Buy is an essential guide -- it offers advice on how to keep your changing customers and entice new and eager ones.
