title: JQuery and validate plugin - how to add a promotional message on submit
body: <p>I need to put a promotional message either at the bottom of the form or in an alert when a user meets certain criteria. I think an alert might be best. It's to do with certain postcodes so I will need to write a regex (I haven't done this yet). It needs to happen when the user clicks submit and before it goes to the server. I'm not sure how to write this and where it should be placed in my script. This is what I have so far if it helps. </p>
  
  <pre><code>$(document).ready(function(){
  $("#orderForm").validate({
      onfocusout: function(element) { 
          this.element(element); 
      },

          shipFirstName: {
              required: true,
          },

              required: true,
          },
