With the Internet becoming an increasingly closer friend to our daily life, online shopping is prevalent and pervasive among college students, white collars, and housewives. In the past, shopping could be an exhausting and time-consuming task for numerous people. However, now we can pick our desired items, compare the prices, and enjoy the service, with a cup of coffee on the table, by several clicks. Apparently, online shopping has become one of the most fashionable and trendy life styles for modern people.

 There are a series of merits for this kind of shopping. First of all, online shopping, to a large extent, helps us to save our valuable time, which can be invested into our work, leisure, and study. Moreover, When shopping on the e-mall, we are exposed to more options at the same time. This advantage enables us to select our desired product in a better price and quality. Further, shopping online is a more eco-friendly way of living because it tremendously reduces our use of traffic, plastic bags, and money, directly or indirectly contributing to the protection and preservation of the environment.

However, it also gives rise to a serious of problems annoying and upsetting us. On the one hand, since it is impossible for us to see and check the goods online, some immoral sellers 

may send us unsound and fake ones, resulting in bigger loss of our money and mood. On the other, when we fill in our personal information and the credit card number online, these privacy are at risk of being leaked and resold to more people, which would bring about some undesired and unexpected consequences.

To conclude, every new-born phenomenon can be a double-bladed sword. I suggest that we be more cautious when we shop online. This can be achieved by more careful comparison, selection of higher-rated seller on the e-mall, and consultation with our more experienced friends.
