I would like to set up shipping on a per item basis. Not based on weight units, just independently per unit. In other words, Item A costs $20.00 ea. to ship and Item B costs $15.00 ea, to ship.

I did figure out that I could use the per item based on weight units but when I order 2 items and it doubles the weight of the order, it only figures the shipping on the weight of one of the units. Can anyone help with this?
