You can sell multiple products. You can also exchange products.

However, if your store has a variety of products such as digital, home, sports and outdoor, clothing and bags, and even beauty and skin care, it will have a confusing effect on your store's crowd label, with an unclear positioning, and it will not deepen the customer's impression of the store. If it is a single product, it is different. For example, Gree and Midea are known to sell air conditioners at the mention of them.
