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 ...

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 ...

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 ...
