title: My Free Shipping is being calculated after tax is added
body: <p>I’m trying to setup $50 free shipping but when I add products that add up to $47.00 the tax kicks it over and allows free shipping. I can’t believe this is standard so I must have something set up wrong. I have the Free Shipping set up under the carriers, FedEx and USPS.</p>
  
  <p>I have “Apply Discount On Prices = Excluding Tax” set in Config/Sales/Tax which seems to be what I’m after. I've also tried the Free Shipping method in Shipping Methods. </p>
