title: Get subscription price of simple subscription product and its sign up fee
body: <p>I am using woocommerce subscriptions plugin. I want to get the subscription price plus the sign up fee of a product of type "simple subscription".</p>
  
  <p>I am able to get subscription price using this function :</p>
  
  <pre><code>&lt;?php WC_Subscriptions_Product::get_price( $product ) ?&gt;
  </code></pre>
  
  <p>However I want to have the sign up fee also, so that I can add the prices together and display.</p>
