title: Change the default Shipping method in Woocommerce
body: <p>I have two shipping methods. First is Free Shipping and second is Flat Rate Shipping for Express shipping for which i charge extra fee. By default Express Shipping is selected in the cart which lead to confusion among some buyers that I do not offer free shipping. </p>
  
  <p>Is it possible to change default selected method to free shipping?</p>
