媒体购物（Media and Shopping）
With numerous technological advances, various kinds of media have been well developed. As a result, an increasing number of people are fond of purchasing goods with the help of media, such as newspapers, radio stations, TV stations and the Internet. Collected By izuowen.com
As we know, every coin has two sides and shopping via media is no exception. On the one hand, it saves much time, money and effort to purchase goods through media since you do not have to go to the shops in person. Besides, you can choose what you want from an enormous variety of goods on display. On the other hand, you may be cheated sometimes by the false information and suffer a considerable loss.Collected By izuowen.com

In this way, we can reap more benefits from shopping via media and reduce the possible harm to a minimum.
