These guys are great to work with. For various reasons we can only ship 1 product at a time. We're not super savvy with installing apps, etc and their team were so helpful! Thanks!

This is a great app and I am surprised it is free. We were getting orders with street numbers missing and then being misdelivered. This app will take care of making sure we don't run into delivery issues. It seems like there are other rules I can create which is great. I think it's a great tool for every store.

We had a number of orders coming through at 0 price due to some tech issue with our inventory management software. Using Block It we were able to block those orders without any issue. We simply created a rule where if the product price is 0, checkout is not allowed – and it worked perfectly! The support team is extremely knowledgeable and responsive. I asked them for support and they developed the needed feature within a single day. Truly impressive service and a very useful app. Highly recommended!
