Function Junction Promos

We have been using the app for about a year and it has been very easy to use and maintain. Highly recommend!

I can't say enough great things about this app and the team behind it. Liz and team are incredible and have built an excellent app. Highly, highly recommend! Thank you! Jackie

Great app that's super user friendly. They also have the best support team!

Function Junction made our transition off Shopify Scripts painless. The app handles sophisticated discount logic cleanly and integrates seamlessly with our existing workflows. Solid product and excellent reliability so far.

Function Junction has been a great replacement for Shopify Scripts. It gives us far more control over complex discount logic while staying fast and reliable. Setup was straightforward and it’s become a core part of our store’s promo stack.

We’ve run several discounting functions through this app, including more complex logic that we previously handled with Shopify Scripts. As we transition fully to Shopify Functions, FJ makes it easy to manage and maintain these promotions without needing ongoing developer support. The interface is straightforward, and it gives us confidence that we can continue evolving our discount strategy without custom code. It’s been especially helpful as Scripts are deprecated and Functions become the standard. Great tool for teams that want powerful discount logic without adding too much dev overhead.

If you need serious control over discounts, Function Junction is the way to go. It unlocks advanced Shopify Functions without sacrificing performance, and it’s become our go-to solution for complex promo rules.

This app is an outstanding alternative to Shopify Scripts and surpasses any other discount app available on Shopify. It’s extremely user-friendly, and when building more complex setups, the support team is exceptionally helpful. Highly recommended!

Function Junction made transitioning off Shopify Scripts super easy! We were able to move away from our complex scripts much sooner than expected—and without any major development costs. Setting up custom bundle discounts was incredibly straightforward, even with our more advanced use cases. The Presidio team went above and beyond, guiding us through the entire process and even adjusting their app to fit our needs. One of the best experiences I've had with an app developer!

Incredibly helpful with getting the app installed and ready in-time for our sale (with 1 day notice)! Performance of the app has been fantastic.
