Fantastic app, highly recommended. We have been using it for years now without a hic. Sabeeh is a great partner to work with and has also built a long list of checkout customisations suited to our store and requirement. A must have for all your Shopify checkout needs!

If you're looking for a solution to customize messages and cart limitations at checkout, Checkout Ninja Blocks is the perfect app! We were facing a challenge on our U.S.-based website, and needed to display a custom message for specific products and regions. Checkout Ninja Blocks not only solved the problem but did so seamlessly. The app allowed us to display a message for our U.S. customers and enforce product limits in the cart based on specific criteria. The customization features were incredibly flexible, and the app provided everything we needed, from triggering messages to limiting product quantities during checkout. It integrates perfectly with Shopify, making it easy to manage and adjust. Fantastic support from the Checkout Ninja Blocks team made all the difference. They worked closely with us to create a custom solution that fit our exact needs. Their response time was quick, and they went above and beyond to ensure everything worked flawlessly. If you’re in need of a powerful checkout customization tool backed by fantastic support, I highly recommend Checkout Ninja Blocks. It’s been a game-changer for our store. Install it, test it, and reach out to the support team if you need any customizations—you’ll be in great hands!
