Cart Block: checkout validator

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 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!!

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.

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.

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.
