Hi Philip,
Firstly, sorry for the inconvenience.
The shipping cost is generated by the website. But there is always something we can do to improve the service, and we are working on it. Now I calculate the weight of each size boards and setting the rules.
Later this month or in the early Feb, we will bring out a whole new charging system. The PCB cost and the shipping cost will be charged by the actual size of the boards.
Thank you for your support!
Best regards
Raymond
