As far as I know, there is no need to stock up and deliver goods when opening a shop without goods, but you must find the goods to deliver to yourself. A store group is a way for a person to occupy traffic by opening more stores. The operation is relatively simple. As long as one store can be made, other stores are equivalent to copying operations.

For example, if you open a shop in Pinduoduo and there is no supply, you can upload the goods from other shops in Pinduoduo to your own shop. When the customer places an order, you can go to the last store to take the order, fill in the information for the customer and wait for delivery at home. If there are after-sales problems, just communicate well. It's just that it's more troublesome to pick up the goods, so many people use the store to pick up the goods with one click, which is more convenient and has many functions.
