title: How to get localized prices with cordova-plugin-purchase
body: <p>In my app, created with Cordova, I would like to do IAP and show prices with local currency.</p>
  
  <p>To do that I used this plugin: <a href="https://github.com/j3k0/cordova-plugin-purchase" rel="nofollow">https://github.com/j3k0/cordova-plugin-purchase</a></p>
  
  <p>On the documentation I have: </p>
  
  <blockquote>
    <p>When you perform the initial refresh() call, the store's server will be contacted to load informations about the registered products: human readable title and description, price, etc.</p>
  </blockquote>
  
  <p>But when I execute the following code I have the product but the price is set to "null"</p>
  
  <pre><code>store.verbosity = store.DEBUG;
  store.ready(function() {
        store.refresh();
        alert("Object:"+ store.get(PREMIUM_PACK_ID));
        alert("Price:"+ store.get(PREMIUM_PACK_ID).price);
   });
  for (var i = 0; i &lt; this.products.length; i++){
        var params = this.products[i];
        store.register({
           id:    params.id,
           alias: params.label,
           type:  params.type || store.CONSUMABLE
        });
  }
  store.refresh();
  </code></pre>
  
  <p><strong>Some informations:</strong></p>
  
  <ul>
  <li>CLI 5.2</li>
  <li>Android 5</li>
  <li>App in closed Beta-test mode</li>
  <li>PREMIUM_PACK_ID === product ID on store </li>
  <li>Refresh &amp; ready well executed</li>
  <li>Tried with one or two refresh...</li>
  </ul>
  
  <p>Does anyone success to get the IAP prices with this plugin?</p>
  
  <p>I try to post here before open an issue...</p>
