Good topic and good comments.

I think this comes down to developing a good relationship with your buyer. Much of this could be nipped if buyers offered a grading system of each supply we sent them. For example, you send in a box of boards the buyer who sorts them could quickly mark feedback to how they were prepped via a 5-star system. A record of numerous positive feedback could give the buyer an incentive to give us higher per pound prices.
