The price of EMS is not good, but the speed is the same, because of the three links between the two sides. After all, they are all on the same flight.
It is not recommended that you take other express delivery. After all, there is a volume of SF, which can guarantee that you have their flights every day. In terms of price, there will be an agreed price if the goods are delivered for a long time. I suggest you call SF for 4008111.
I do international transportation and often cooperate with express delivery. I hope I can help you.
