Taobao delivery, people in the same city buy my things, and it takes three days to send them from Shanghai. How should I reply to the customer?

Just say that you are the online agent of the factory and your online order needs to be submitted to the factory. In order to deliver the goods to our agent in a unified way without causing financial difficulties, it takes three days to arrive at our agent, and the goods will be delivered to you as soon as they arrive. I hope you will wait patiently.
