Berrett-Koehler Publishers review for PowerX ‑ Functions Creator

This app has done for us what no other app could. On top of the great flexibility of the app, the team has been so helpful. They've even gone as far as adding a filter option for me to be able to do something I need to. I've been so impressed by this app and the team running it. I strongly recommend this app if you need to run complex discounts.
