I have a customer that is selling olive oil in 2 different size bottles. They plan on using only box size.
This box will hold 4 200 ml bottles or 2 350 ml bottles.
My challenge is when a customer orders more than what will fit in one box then it needs to add additional cost.
order is 4 200 ml shipping equals $15
order is 5 200 ml shipping equals $15 (x2) = 30
Hope it makes sense what i am asking.
