My business requires that I give my customers a real time price on my website.. I am trying to get various factories in China to give me exact price of various items.. I only offer custom items to my customers spec.. but I still need to know rough prices.. As I am in profit.. If the factory can't give me full prices would this mean they are a trading company? For example I need to know price of a given item from 10mm to 14mm, 15mm to 25mm etc... I am getting really tired now as dealing with some of these factories is like dealing with children.
