Fabio has been so helpful in getting us set up to use cartblock. Our situation was a bit complicated, and he sorted it all out for us! This app does exactly what it says..it provides a clean way to block customers from checking out based on rules you set up.

I stumbled across this APP. For me it is fantastic and after 1 week of using it it has generated some good income which I was not having before. For me a wanted to block certain products from being sold to specific countries, rather than blocking the entire country. Shopify as standard blocks the whole country by removing the specific country from checking out..... however Cart Block does it differently. Well worth the monthly fee. Tech support was great. I had to use theor tech support and I was quickly invited to a video call and within a few hours the initial issues were sorted and the APP was creating turnover! Thanks for writting a great APP.

This a very promising app and beneficial for merchants who need to block certain customers or orders on their store. The support team is absolutely amazing and took the time to meet with me to resolve some issues with the app. The reason we gave it 4 stars is because there are still some issues depending on how you decide to block customers (there are multiple scenarios you can choose from). This isn't necessarily an issue with the merchant itself as there are some limitations with developing an app for Shopify. However, if you run into any issues we recommend contacting them for a one-on-one call before giving up. We highly recommend this app. There are not many options for this functionality (and honestly this may be the only one).

i was having issues with scammers testing stolen credit cards on my site and i wanted to prevent this. i reached out to shopify for assistance with getting v3 added to my checkout but per shopify it's only available to those on the plus plan. after a few days of research i ran across this app and tested it out - i had to reach out to customer service to assist me with making sure the app would prevent the card testing and after a few emails, we set up a call so that we could make sure the app would in fact prevent card testing. during the call customer service noticed that an update to the app was needed and made me aware that they would update the app and get back to me. less than 5 hours later i received confirmation that the app had been updated, allowing me the ability to set new rules. since then the almost hourly card testing attempts have stopped. i am so very grateful for this app the customer SUPPORT. if you have card testing issues on your site, this is the app for you!

Excellent customer support, always respond within a few minutes and solve all issues. The app works as it should. New features are always being added and feature requests are also taken as feedback for development. Highly recommend!
