How to create a discount reminder pop-up in the cart?

Shopify Apps

Topic summary

Goal: Trigger a cart pop-up that alerts shoppers they’ve earned an automatic discount on Collection B when they add any item from Collection A. The discount itself already works; the need is a reminder/announcement based on this cart condition.

Status and attempts:

  • Multiple pop-up/upsell apps were tested but none supported the needed conditional display logic (Collection A in cart → show discount message for Collection B).
  • Request is for an existing, ready-to-use app that can do this.

Suggestions offered:

  • One response recommends a custom script/app or seeking customizations from app developers; advanced apps with flexible rules might help.
  • Another participant offered to build a custom plugin and asked about timing.

Constraints:

  • Limited-time fundraiser already underway; needs an immediate, temporary solution (through year-end).
  • Preference for an established app to avoid custom dev time/cost and to reduce risk of conflicts with existing cart apps (royalty fee calculator and a custom discount app). Extensive testing would be required.

Outcome:

  • No specific app recommendations surfaced.
  • No solution adopted yet; discussion remains open.

here’s the specific use case:

when any customer adds an item from collection A to the cart, an announcement pop displays that informs customer that they have earned an automatic discount on anything from collection B. This discount function is already working; I want to remind them of this automatic discount in case they didn’t see it or forget.

This is seems so simple, but none of the pop-up or upsell apps I’ve tried out has this display logic.

edit to add: Does anyone know of any existing app that solves for this?

thank you! Lizzy

Hi @lkstar ,
This is Theodore from PageFly - Shopify Page Builder App.

You’re searching for a specific feature on Shopify: a pop-up notice that appears automatically and informs customers of an automatic discount on Collection B when they add a product from Collection A to their cart. Since conventional pop-up or upsell apps do not have this feature, you might need to work with a Shopify developer to design a bespoke script or app in order to implement this. As an alternative, look at sophisticated apps with features that may be customized or get in touch with app developers for unique changes. Bringing together various apps or interacting with the Shopify community forums may also yield beneficial outcomes. Effectively informing clients of the discount through a pop-up based on their cart activities is the primary problem, and a unique solution appears to be the best

I’ll be so happy if my suggestion can help to solve your problem. If you have any further questions, please feel free to tell me.
Best regards,
Theodore | PageFly

thank you. I should have clarified, I am wondering if there’s an app out there that I’ve missed. This is a limited time fundraiser and I’d prefer to avoid investing the time or $$ in custom coding.

thank you, Lizzy

Let me see if I can create a custom plugin for you. I read in the comments below that it is a limited event, do you have a time you need this by?

HI, thank you for replying. This campaign has already started. I appreciate your offer to create a workaround. I was hoping to go with an established app because I need it now, I only need it through the end of the year, and I’m concerned about anything custom interacting with other apps in my cart (particularly the one I use to calculate royalty fees but also I had to use a custom discount app to execute this program.) .. there are a lot of use cases to test… though I guess I’d do that with an app, too…
