Old Price Alongside New (Sale) Price

Searching the forum I see this isn’t available in ST even though the functionality was provided in SP. I’ve designed the site

https://www.custarddesigns.com (WP 3.9.2, ST 6.6.4)

for my wife. Now those who are married and male will know that one desires an easy life – a life without grief and nagging. I’ve had my ear bent today about this option not being available. All she wants to do is reduce a load of stock and add to the ‘Sale’ category. In SP she could add the new price but she can’t do this in ST and she’s p*ssed. She tells me it’s not good enough to add the old price into the description.

Please please tell me that this will be included in the next update or that there’s a plugin available (Richard Bonk I’ve checked your site but one’s not available.. pls develop!).

I would’ve thought showing the reduction/saving was pretty fundamental to an ecommerce site?

Grateful for help.
