Update - All good. The reason I couldn't get through is timing. While it was Friday in my time zone it was the weekend there. Support has contacted me and we are working toward a solution Reviews indicate excellent support but I can't get past the screen that only shows How To videos. My first attempt at a validation blocks ALL cart entries. I need help fixing it but can't get any useful help. I know I'm doing something wrong but I don't know what

There are a few things that can be tricky to set up...BUT FEAR NOT!! This support staff goes above and beyond to make sure you have the settings just right. Sometimes it takes a couple Validations to get things set up. The only way you are getting frustrated is if you don't use the in app chat to get connected to those who can help you most. Can't figure it out...they will help! Great features and works flawlessly so far!

I just started using the app and I don't know whether it's going to work or not but the support I received from the developer was the best experience I had with any app on shopify. 5 stars for the support and hopefully 5 stars for the app

I have a few products marked as $0 in my store because I am not permitted to put the pricing online, and even though I customized the "Add to Cart" button to say "Contact for Pricing", people would still click and check out these items at $0 (products have a $4,000-$14,000 value range). This app allowed me to set a rule that products below $1 cannot be checked out and it completely stopped the $0 orders! Took me about 3 minutes to set up once I installed the app, super easy!!

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).

10/10 recommend this app - very functional and amazing customer service! I had a very specific and niche use case, I emailed customer service and Andrea was not only very prompt to respond but even released an update to his app that would allow it to work for our use case. Thank you!

Dealing with bots abandoning checkout because they are attempting different credit card numbers. This app allows me to set up rules to block these bots from checking out. They will still try but their attempts will be futile, so if they come across and use a card number that works, it will be blocked. In time they have slowed down as I believe it sees my store as not being able to do what they want. It is working when you can identify bots as having similar profiles (in this case they all use the same fake address and phone area code) if bots change their strategy you have to find the commonality and set up another block.

Love Cart Block app. This is by far the most versatile and flexible in terms of blocking rules. Many apps promised email, address and phone number blocks but will require you to entre the exact value. Cart Block is the only app that offers "fuzzy block" rule where you can block checkouts containing certain values. My store was hit by card testers, who were using my payment gateway to test stolen credit cards. With Cart Block app, it mitigated the risk with payment gateway. I tried many apps like Blockify, BoosterMark, Negate etc. None of them were as flexible as Cart Block. When I reached out for support, Andrea replied promptly and implemented additional blocking parameters for me to use. This level of customer-centric approach plus the flexibility of the app means that I was able to ward off attempts at credit card fraud. I will highly recommend this app to any merchants who experience card tester fraud issues, or anyone who requires product or geo blocking rules implemented at checkout.

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!
