We have a drupalcommerce website through which we sale
- iptv box
- qwerty key board
on adding first product it adds 15 dollars( base rate ) + 5 dollars per item in cart, so if we have 1 item in cart the shipping is 20 dollar but if we have 2 products the shipping will be 25 dollars and so on.
problem is, we want to setup separate shipping rate for qwerty key board if there is only a qwerty key board alone in cart the shipping must be 5 dollars.
I hope this can be done through shipping rules
