Thread: Normal price to get automated strikethrough

Normal price to get automated strikethrough

I am developing a deal website - my 1st custom field is the Ad Title the 2nd one is the Deal Price these two are chore required fields.
The 3rd custom field I created and it is the Normal Price

Eg:
Ad Title: Adidas shoes
Deal Price: $50
Normal Price: $100

I would like the $100 for the Normal Price field to have a strikethrough through it like when you go to a sale and the sale item has 2 prices Was and Now and the Was price has a line / strikethrough through it showing you that that was its price but the line through it indicates that it no longer is and that the sale/deal price is the price that it is selling for.

Any help with this would be appreciated - I am using childthemes - im just not sure how to do it or where the function is for this field I created.

Thanks
