What is the membership stamp price?

Stamp duty is a kind of tax levied on the documents signed and received in economic activities and economic exchanges.

the general printing price means that the tax on this part of the goods is borne by the merchants themselves, so it is cheap, and the discount of the goods for members only has nothing to do with this. When you say the member printing price, you mean that members can enjoy the printing price for some commodities, understand?
