Sam’s Club seems to be unaffected by the environment and cycles. As Chinese retailer stores enter an iterative state, Sam’s offline customer flow has not been affected even though online orders still surge.

Member Sam's needs are constantly iteratively updated and upgraded. To meet customer needs, it is necessary to understand customer needs in advance and then display them in advance.

To have a vertical business model is to make the goods find people, and it is easier to attract customers with good quality and well-packaged goods. There is also attention to the placement, neatly placed products are easier for customers to notice, roller shelf can better help the placement of products, make the products more beautiful and tidy, and attract customers' attention.

Sam's current ability to maintain a stable flow of customers depends on his unique membership system. Sam has a fixed service population, and under the condition of quality assurance, he can continue to discover this fixed population and attract more people.
