Outstanding support and a fantastic app! Reymar is kind, professional, and incredibly skilled. When I reached out to customer support, he resolved my request in under 10 minutes, which is unbelievably fast. The app itself offers great flexibility for customizing your shop. I highly recommend this app and their other tools as well!!

While the app does have certain limitations, their top-notch support more than makes up for it. App developers go above and beyond to provide alternative solutions for custom functions. Since the deprecation of Shopify Scripts, this app has been extremely useful with building out custom rules for our Plus store. Highly recommend!

Was looking for a replacement for Shopify Scripts to get a bit more detailed and complex discounting enabled, and this was perfect since we needed to find something for line item properties. Huge shoutout to Reymar.
