I am an online shop owner. So everyone still has some experience! 1, generally speaking, courier companies have bags for express delivery to hold your clothes. Look at the competition in some places, some need to charge, such as a bag of 30 cents! Most of them are free. 2. There are two possibilities for the list. If you need to deliver more goods in the future, you might as well go directly to the company that often delivers goods and ask him for some invoices, such as Tong Yuan, SF, EMS and so on! Some are free, and some are one yuan. Generally speaking, postage is much cheaper! You can have it again. It's better to pay the postage first, because the charge before delivery and the charge after delivery are two concepts, and there will be many differences. In this way, the customer who receives the goods there will think that you are deliberately squeezing him, which is not good either! 4, look at the courier company is not far from you, just take it yourself. For example, I have to deliver goods every day, and it has been fixed that they will automatically pick up the goods every day. It seems that you are not familiar with express delivery. There is a courier for you, and a copy is attached to the courier. Don't worry!
