For our supplier ,we hope to the material price going down ,so we can use less money to buy material ,and the customers can place more orders .but sometimes the material price going base on the market .more demand  and less supply ,will made the product price be higher ,less demand but more  supply than need ,it will made the price be much cheaper .

But in  July month ,the demand should be less ,but why the lead price going up ? what happend ?
