Hi,
We are looking to ship items by using USPS flat rate boxes, but the items are different sized so various amounts can fit in a box.  9 12 oz jars can fit in the smaller box while 24 4 oz jars can fit in the same box, so it seems like we need a different shipping logic by quantity for each jar size.  Is there a way to provide custom logic for different products?
