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.
