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 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!!

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.

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.
