I want to apply discount on shipping rate. For example if cart subtotal is greater than $125 then there will be a discount of $17 on the shipping cost. I have created shipping cart rule in admin but the rule gets applied on the cart subtotal, not on the shipping cost.
I have selected the options "apply to shipping amount" as yes and "Stop Further Rules Processing" as no.
Do anybody have idea about how I can do this. Any help will really be appreciated.
Thanks in advance.

We did this recently with a sort of hackish use of the sales rule admin panel.
In your rule, under 'actions', in the panel 'Apply the rule only to cart items matching the following conditions', create a condition that can never actually occur. We used sku == 'invalid'. As long as you have selected 'Apply to Shipping Amount', it will take the discount only from the shipping costs. It will not match any items in the cart, though.
