How much does it cost to mail more than 80 kilograms of clothes from Zhangqiu, Jinan to Shanghai through logistics? Is it cheaper to use postal service or in-kind service?

Don't go as long as you are packed and tied up. If the quantity is not particularly large, it is usually thirty to fifty. There is a deviation in logistics charges. I suggest you go to a regular large-scale logistics, where there are many trucks. It will be safer and cheaper. Small logistics what is resale to other logistics and then transportation.
