Do you have minimum order value?
Apart from material volume cost, there are serveral ingredients in order pricing:
Per Material Minimum Order Value
The minimum order amount is $30 per material(SD and HD resolution are considered as same material) excluding shipping cost. Which means if your parts manufacturing cost is less than $30, we will still charge $30, so it’s more economic to order multiple copies if your part is cheaper than $30.
Per Part Minimum Order Value
Since each parts has to be post processed manually, we normally charge extra per part to cover the labor cost. Normally it’s $1.2 per part, but if the parts are too complicated, the per part fee will be higher.
