Shipping configuration

I know what it cost to ship one item coast to coast (US). I want to set it up so that is charged and an additional $5. is added for every additional set that is ordered. I have real time UPS set up but that doesn’t change to reflect enough difference in shipping. I have the box dimension configured for 1 set. Should I remove that? :confused: :confused:

Can’t you add a shipping surcharge per product?
