We offer free shipping for deals >$X(automatic discount ). if the customer returns items that make the deal <$X, canceling by doing so the logic of the discount that he was entitled to), we charge for the shipment. we do so by subtracting the shipment cost from the refund due. is there a better way to go about this? so we will have a way to check how many pay shipments we had. (as of today the shipment payment is only in the client note of the deal. the shipment payment was invoiced in the original order
Thanks, Gil
