IC 4.8.3 using GNDRES and GNDCOM ups shipping methods how could i calculate shipping based on a case being the max size and so that single bottles and six packs are combined to make cases? weight is based on individual bottles item qty options are 1, 6, 24 right now if people order more than 150lbs (3-4 cases depending) the ups fails out of course. thanks a bunch! pat
