That is why we don't follow the system at this time but if its abused we will have to change that. But all large, small or green and color boards to us is the same price. With the information we have in front of us we don't see an issue with "mix" boards. But if someone sends us only color pricing or would like to send us only one type of board they need to send us a e-mail first to find out the pricing that it will be for that.
