It depends on what you are wholesale. Some products are heavy, so the shipping cost is naturally expensive. For example, a box of food costs hundreds of dollars.

If the wholesale quantity is small, it is basically delivered by express delivery, which is not cheap. If you can find a carpooling logistics, you can use logistics, which may be cheaper. If the quantity is large, it will definitely be delivered by logistics, not express delivery, because the cost is too high.
