(71.) [The internet is profoundly(深刻地)changing consumer behaviour.] One in five customers walking into a Sears department store in America to buy an electrical appliance will have researched their purchase online—and most will know down to a dime what they intend to pay. (72. ) [More surprisingly, three out of four Americans start shopping for new cars online, even though most end up buying them from traditional dealers.] The difference is that these customers come to the showroom armed with information about the car and the best available deals. Sometimes they even have computer print-outs identifying the particular vehicle from the dealer’s stock that they want to buy.

Different countries have different habits. (73. ) [In Italy and Spain, for instance,people are twice as likely to buy offline as online after researching on the internet.] But in Britain and Germany, the two most developed internet markets, the numbers are evenly split. Forrester, a research consultant says that people begin to shop online for simple, predictable products, such as DVDs, and then graduate to more complex items. (74. ) [Used-car sales are now one of the biggest online growth areas in America.]
