As we know, online shopping has became universal. On the one hand, online shopping is very easy, since we don't need to go every shop to choose, and its sort is very great, which save much time for us. On the other hand, online shopping is not very safe, besides, we cannot know what the goods are really like before we receive them. As far as I am concerned, I believe online shopping is necessary. We can spend less time shopping and we can search what we want by keywords quickly, we can shop every time and everywhere, what's more, we can choose among all the shops. when it comes to its drawback, we can exchange or return the goods if we really don't like them, and it will become safer and safer with time goes on.
