I have shipping defined by invoice total $$, and we offer free shipping for all orders over $30. Well, customers are getting free shipping on items that were originally over $30, but are now discounted below $30.
Is there anyway to change this so that shipping is determined by current (discounted) price and not the original price?
Please reply as I need this issue solved also 
Think I found it!
Add this code in fn-cart.php on line 1319
$cost = $cost - $cart[‘discount’];
Then shipping costs are calculated based on discounted price
