求翻译：Undoubtedly speaking, online shopping has many advantages. Firstly, compared with traditional shopping, it’s very convenient. What you need to do is just clicking your mouse and waiting instead of going out by foot or driving. Secondly, more choices than real store are another attraction to customers. However, in spite of convenience and more choices of online shopping, we cannot turn a blind eye to its disadvantages. Obviously, quality problem is its first disadvantage. It’s common that articles aren’t so good just as they are described online that customers always buy fake commodities. In addition, it’s troublesome and annoying for many customers to make a change when they are not satisfied with what they bought online.是什么意思？
