Apply free shipping to total price

Question

I’ve got a problem. I’ve got at customer who has free shipping for orders on $200 and over.

The problem lies in the discounts she offers. 1 type of discount is the 10 for 9 price. So if the Subtotal reaches $201, then the customer gets free shipping, and if the customer has bought 10 for 9, then the customer will get the discount, and the Totalprice will end on maybe $175,-

So the customer will get at discount and free shipping, because of the cart rule is applied before the discount.

Is there any workaround / coding modifications I need to do, to correct this matter?

Thanks in advance - Thomas
