We needed an app to block the use of additional discounts during our site-wide sale, and this app was super easy to use. Only a few steps to implement and the customer service team was really responsive and helpful. Highly recommend.

Great, help from Customer Support for setting up the rules.
— Freddywear
Possibly the most useful app right now in the store. Fast and reliable. I am zero tech savvy so I contacted support and in lest than 15 minutes all the rules I wanted to implement were running smoothly. 10/10 app. Looking forward to launch soon. Many thanks.

No free plan, they mislead the users by having a free plan, but then you find out it's for dev stores only. That's very misleading. Pricing is insane for a such app. I mean... I need to block 1 customer and for that I need to pay 9 USD every single month? Crazy.

I needed a tool to exclude a zip code from being able to choose shipping. This worked perfectly! Shahriar was very helpful and quickly got me the result I had been searching for.
