Show original price and discounted price? I'm using this module: Commerce Discount to create products discounts. In the products list view I'd like to show both prices: the original price and price with the discount. How can I do this? 

I found this module:   https://drupal.org/project/commerce_price_savings_formatter but it doesn't seem to work with the Commerce Discount module.
It does work with the discount module. In fact the moudle was built with that one in mind. Install Commerce Price Savings Formatter and go to your product types's display settings and change it as per the screenshot.
