At present, on-line shopping has gain popularity in the society. Almost every young man has practiced buying stuffs via the Internet; more importantly, some are so addicted to on-line consumption that they even purchase private cars at virtual 4S stores.

　　On one hand, daily products sold on line are usually much cheaper than those displayed in the shelves. Also, it is convenient for consumers, especially commuters, to obtain what they need in this way. On the other hand, buyers cannot check their intended on-line products. Thus, what they shall receive are probably not in accordance with those introduced in the webpage.

　　In my opinion, on-line shopping creates both merchants and consumers an efficient and economical way of selling or buying commodities, so it should be encouraged. And related agencies need to improve the supervision, ensuring that the consumer benefits will not be damaged.
