　　移动设备上购物比PC端价格高

　　CBS News: For years now, merchants have tracked individual online shopping habits to personalize their websites and attract customers. That also helps them make assumptions¹ about income and spending power.

　　But a new study says some companies are going beyond that by using what they know about each shopper² to set different prices for the same product.

　　You may have noticed while shopping online your computer seems to know exactly what you're looking for. That's because companies track your search and purchase histories to make guesses about what you like.

　　But a Northeastern University study shows companies are also using information about how you're shopping online to customize prices.

　　Asst. Prof. Christo Wilson explains."Many E-commerce sites will give deals or change the prices for people using specific devices or browsers³, or will change the order of search results to highlight more expensive items."
