Show automatic discount rate on product page and cart

Topic summary

A merchant using Shopify’s automatic discount codes faces visibility issues with promotional pricing. The discount (€5 off a specific collection) only appears at checkout, not on product or cart pages.

Core Problem:

  • Discount code applied via URL parameter works functionally but lacks visual indication until final checkout step
  • Standard articles about compare pricing don’t apply since this uses automatic discounts, not manual compare-at prices
  • Merchant uses Shella theme template

Attempted Workaround & New Issues:
A second user with the same Shella theme tried implementing a custom solution using compare price logic to display discounted amounts and sale labels. This created three new problems:

  1. Sale labels and discounts disappear when changing product variants/sizes (requires page refresh)
  2. Cart popup displays full prices instead of discounted amounts (includes screenshots)
  3. Shopping cart page shows discounted item prices and totals, but total remains undiscounted

Status: Unresolved. Both users seek either a native solution or confirmation whether a third-party app is required to display automatic discount rates on product and cart pages.

​Hi team Shopify!

I have created a promotional Discount Code that applies to a specific Collection. Once someone enters the website with the url with the discount code applied, the discount rule is €5 off on all products within that collection.

The discount is only visible when i go to the final page of the checkout (see screenshot). It’s not visible on the product page nor cart. I am not able to figure out how to get the discount to show on the product page and cart page. I am using the Shella Theme template.

All the articles i have read seem to apply to products that have a different compare price. I do not have a compare price set up, since i am using the Automatic Discount. Is there a way to do this? Or do i need an app?

​Thanks for your help!

Hi did you solve this issue? I’m experiencing the sale problem with Shella theme …

I did same step ahead hacking the logic of compare price, basically I use compare price to show the discounted price according to the automatic price and the SALE label in the product page.

The problems I have now are 3:

  1. if I change the size/variant of the product both sale label and discount disappear and I must refresh the page to show them again.

  2. the popup My Cart shows full item price, but the total is discounted

  3. Shopping chart page instead shows discounted item prices and discounted total
