Amazon has brought a new model of sales and business to e-commerce and retail. In fact, the earliest e-commerce in my country was not Taobao, but Amazon. And it was a B2C type. In addition to taking the lead in e-commerce, Amazon also set a good example, because Amazon is known for its high quality, rather than taking the lead with low-quality goods, which is exactly the opposite of Taobao. As for the retail industry, it is a shock to the traditional retail industry, especially high-end goods such as clothing and shoes. But it is not the case for daily necessities.
