Shipping by Wieght
I have setup 3 zones for my shipping
Each zone has a different base rate for shipping but includes the first 15kgs but now I need to add £xx.xx per kg above that original rate.
Is there an obvious clalculation Im missing here or do I really have to add each increment up to the most you could really imaine ie 100 kgs that would take masses of rules.
Thanks for any help or pointers.
