　　What vivid and thought-provoking pictures! We see, in the first picture, that a woman holding a computer is paying for something with delight since she is led to believe shopping on the internet is saving, while in the second picture, we see that a man is going crazy for all his money is took away by the computer.

　　With the development of science and technology, it is much more common for people to buy goods through different kinds of media than before, especially the internet. Shopping online is welcomed by most people due to various reasons. From the perspective of consumers, it can save time or money for people. For retailers, it can cut costs for those without much circulating funds. However, there are still some defects in online shopping. First, compared with face-to-face deal, it seems less reliable and trustworthy. Second, people will lose the fun of bargaining and lose their money silently.

　　In my view, although online shopping brings great convenience to us, we still should be careful when we “go shopping” on the internet. We should check the information released by the merchant. Only in this way can we fully enjoy the convenience brought by online shopping without the concern of being cheated.
