Has anyone implemented "Sale price" functionality where the original and sale price show?

I did it via a theme change. I exposed the original price's price level and the new sales price's price level (eg. PriceLevel5) to the details field set, had both of them showing on the relevant templates and put some styling on the original price to give it a strikethrough and make it smaller.

@Tariq Sanjakdar Wow, that's simple and elegant. Thank you! 👍🏻🙂
