      data: { updates: cartUpdates },
      dataType: 'json',
      success: function(stuff) { 
        window.location.href = '/cart';
      }

    $.ajax(params);
  })(jQuery);

Anyway to adjust the code above to add a "processing and handling" fee of $19.95 to the cart when they add a product?
And maybe also have a small image thumb to represent what the fee covers there as well?

Thanks for any help!
