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!

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!
