I was looking for an app to prevent discount abuse and stacking and to add fees on my store. Instead of paying for 2 apps for this, I shifted to this single app. Really helpful for me. James helped me set it up and promptly responded whenever i asked for help. Support is great even on the free plan.

Needed something to stop discount abuse and unwanted visitors, and this did the job without much setup. Been working well for us so far!

Finally, an easy way to add custom fees without coding. We use it for handling, warranty, and COD surcharges, without paying any commission on the fees we collect. The rule-based setup gives us complete control over when and how fees are applied. Now we can use a single app for both checkout rules and adding extra fees instead of managing multiple apps.
— Florist Shop
Really handy app for protecting my Shopify store. I use it to block certain countries/IPs, control checkout and discount rules, and protect store content. Everything is easy to set up, and the support team is quick and helpful.
