How much does it cost to express from Jiangsu to Guangdong?

It is calculated by weight. Generally, the first weight is 10 yuan/kg, and the second weight is 8 yuan.

If you are an online shop (novice), you can certainly bargain with the courier.

There is no best express! Just relative.

Bargaining with express delivery is also skillful. It's best to pack a lot of packages (or fakes) first, and then give one or two of them to the courier. Tell him you have a large quantity of goods, show him those packages and ask him the lowest price he can give you.

I come from Shanghai. My delivery price is Jiangsu, Zhejiang, Shanghai and 5 yuan /3kg. Other regions 10 yuan/kg.
