I want to add a discount price tag to the cart page that says how much people save when they add a product to their cart that’s on sale. I don’t have a programming background, so guide me briefly. A screen shot is also attached for reference.
Currently, I am using the theme Ella 5.1.0.
Hello,
Are you using Shopify Plus? Unfortunately, as of right now you can only access the checkout.liquid file if you are a Plus subscriber.
If you are on Plus, we would be more than happy to perform these edits for you.
Let us know 
I’m not a Shopify Plus user. I want to display the discounted price heading on the cart page and the checkout page.
I want to make sure that customers understand how much money they may save by making purchases during the promotional time.
