View the original price, the discounted price and the discount percentage I am currently working on a newsletter and I want to display the prices of my products there. How to recover the original price, discounted prices and the discount percentage. I wish to put three different value to place my letter and apply a different style.  

With this line print render($content['product:commerce_price']);
it displays the three values. But I would separate them.

So what line of code do I type to get the original price, then to get the discounted price and then to get the discount percentage?
here is a product page of my site enter link description here

thank you
If this is Drupal 7, you can use the Commerce Price Savings Formatter.  This extends the price field to show the "list price" and "sale price" and automatically calculates the percentage.

The module page links to a video explaining how to use the module.
