According to a survey, online shopping is more and more widely used with the development of science and technology. On one hand, online shopping is so convenient that you can buy things whenever you like as the online shops are open for 24 hours a day. What’s more, you don’t have to waste a lot of energy and precious time to go from one shop to another to choose what you want to buy. In a way, it is often cheaper to buy goods through the Internet as well. On the other hand, if you buy goods online, the quality of goods and the safety of your credit cards are sometimes doubted. As a result, some websites can not be totally trusted, so be more careful and make a wise decision when shopping online.
