Is it possible for me to set up a Flat Shipping rate per box vs. per product? I have a product that is the same shipping rate whether it is 1 product in the box or 3 in the box. Can I set a flat rate shipping to charge buyer the shipping fee based on the number of items purchased? I have only seen the option to add a flat rate to a product which would then overcharge my buyer. If the buyer purchases more than 3 items can I create a "rule" that charges them for the amount of boxes needed to ship the items? Example: Can I set a rule that says shipping is $10 for 1-3 of a specific product, and if there is 4-6 it is another $10? Can I do this for more than one product?
