- I have a flat rate of $2.50 for every order.
- I have extra +$1 for every extra item added to cart.
So, if I order 1 item, total shipping is $2.50, but if I order 2 items total shipping is $3.50.
My problem is that in 2nd case, I get total shipping of $4.50 for 2 items instead of $3.50. It calculates the +$1 for both items.
I added the rule condition
Total product quantity comparison to apply +$1 if quantity is
> 1. So if I add only item, it doesn't calculate the extra shipping, but as soon as I add more items, it calculates the extra shipping for initial item.
