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.

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.
