I've had the habit of shopping online for over 20 years. So, I witnessed the whole development of ecommerce. At the very beginning, most people didn't believe this new business model, they tended to go to brick and mortar stores to buy things, especially for clothes. The clothes sold in physical stores were usually very expensive, but were cheaper online. I started shopping online due to the lower prices; for the most essential needs. Then a good reputation was built for online shopping. As shopping online rapidly developed, more and more brick and mortar stores closed. Many people lost their jobs, but new jobs were offered, such as express delivery and there's a big amount of deliverymen. Nowadays, not only clothes, but also food can be bought online. The reduction of shopping time makes online shopping as convenient as shopping in bricks and mortar stores, but in much lower prices. Nevertheless, whether or not the items bought online fit the customers well or not is still a problem. Though many online shopping APPs allow customers to return items without any reason in seven days, the cost accrued during the return is another new problem. This new problem makes the quality of goods worse than before.
