title: WooCommerce - Product Add-ons (Extension) not effecting price in cart
body: <p>I am running the WooCommerce extension "Product Add-ons".  </p>
  
  <p>I have created a catering website and ideally, the customer should be able to click the "Platinum Upgrade: Add a fresh fruit cup and a chocolate dipped strawberry to each box" to add $2.00 to the item's price.</p>

  <p>On the product page, when you click that checkbox, the price LOOKS like it changes, but when you go to look at that item in your cart, it DOES NOT have the increased price for the add-on.</p>
  
  <p>I have tried submitting a support ticket to WooThemes (where the extension was purchased), but it's been ignored...</p>
  
  <p>I am not skilled outside of html5/css3 and I have no idea where to even begin to fix this.  Any direction would be MUCH appreciated.</p>
  
  <p>Thank you</p>
