I have a question. I would like to add a price tag that says how much people save when they add a product to their cart that’s on sale. I have attached an example, which is actually an ‘automatic discount’ that applied to the cart. I just want to implement this for every product that people add to their cart when it is on sale.
I don’t see why not. If you’re referring to your cart page, you can simply show {{ line_item.price }} with {{ line_item.final_line_price }} below it. I usually look over needed objects here: https://www.shopify.com/partners/shopify-cheat-sheet
you might be using {{ line_item.original_price }} swap it for {{ line_item.original_line_price }}. line_item.original_line_price should return “line_item.original_price multiplied by line_item.quantity”.
