In different periods, the experiences of shopping online are different. I still rememeber that there were only a little people went shopping online 20 years ago. They could buy some fashionable clothes online which easily attracted other's attention. Meanwhile, there were also just a few people opened online stores. Later, more and more people tended to go shopping online which improved the express. Deliverymen became a new type of jobs. Nowadays, if a person who doesn't have a job for living, the first thing that comes into their mind is to open a store online to sell some items. The limit of being an online vender is really low. In that case, someone begin to sell fakes online. It's hard for the web managers to supervise their activities. They usually have many accounts. The good sideisthat we can buy anything online. People live in developing or developed areas can have the same resources on clothes,study, or even medicine.
