Generally, the sample of AOC Cable is provided by Wuhan Rayoptek Co.,Ltd without the exemption from freight fee. Taking the distance between export destinations and the port and other overhead expenses into account, the cost of delivering the sample may be higher than the unit price of the sample itself. From delivering the sample out of the factory to customers' hands, the whole manufacturing process can be completed requiring the combined efforts of a great number of people including warehousemen, shippers, and after-sales service staff. The cost of manpower is necessary.
