In order to see product price via the Commerce Price Savings Formatter, you need to change the display of the product price field from "Formatted Amount" to "Format Amount with Savings". The module also provide similar display for the field in Views.

What I was not able to do yet is to have the price formatter work on the cart summery line item so customer will be able to see total savings on the entire order. Anyone have suggestion for how to do that?
