This is a very simple but effective app, its a little clunky but gets the job done perfectly for what we need blocking certain postcodes for certain products. They are always on hand to offer support as well and fix any issues promptly.

This app was easy to install and set up a rule/condition. Live Chat support was super helpful to make sure I set it up correctly.

I had some confusion setting up the rule. I was assisted in live, the dev immediately agreed to meet on video call and helped me out. He test the rules and promptly responded to me by email. Highly recommended !

Great set up! The ONLY app I’ve been able to find to prevent customers from returning to buy a limited-time deal. Very helpful customer service! Responded quickly and clearly laid out the steps to install the triggers.

If you are getting attacked by bots with $0 orders, you probably have been spending so much of your time being distracted or unsuccessfully looking for a solution. Cart Lock was our answer. I wish I had known about it sooner. Once set up (which is super easy), not once single bot has been able to get through. Thank you, thank you, thank you Cart Lock! Now I can focus on growing my business without those bot distractions all day! :)

Sometimes the app is a little tricky to use, but that is perfectly fine because their support is amazing. Anytime something hasn't worked the way I wanted to, the support has been patient and dedicated to getting the problems resolved. They answer quickly and are 100% reliable. You don't get this kind of dedication with some apps, so I really appreciate them!

We struggled for months to find a robust but simple souloution to customers abusing a free bundle offer we had. With the engineer and help and thoughtfulness of KlinKode, they were able to help bridge a solution to make this happen. Another app was needed to be used in conjunction, but with both apps we were able to achieve exactly what was need, and this wouldn't have been able to be done without the thoughtfulness KlinKode designers. They were there every step of the way and this app is so useful. I highly recommend this team and APP.
