If you have free shipping after x on magento then apply a discount coupon code that brings the total below x the customer still gets free shipping. Here is a corrected file for magento 1.9
This was based on a post that I can’t find anymore.
You will need to change this to the ID of the shopping cart promotion that you are using for the free shipping rule. if ($ruleId==’2′)
