In current society, shopping online instead of in markets or shops has become much more common than ever, with unstopable questions asked all the time. Some insist that this way is more convenient, fast, easy and time-saving, and they find it advantageous to make a purchase within a few clicks on the mouse and keyboard through Internet on one computer under their own condition. Nonetheless others keep having doubts about whether it's actually safe and trustworthy to do this shopping online thing, most of which stick to their former choice of buying stuff where they can really touch or smell or feel with their own senses. I believe that with these years's endeavors made on establishing a stable and complete online shopping system, it's time for us to do it, or at least have a try, after all, whatever we choose to do, shopping online has been more and more popular around us.
