This app is very easy to set up and offers a lot of options to block shipments to PO Boxes. It has an option for blocking by product, but did not have an option for blocking by collections. When I asked Jason about this, I was amazed that in a couple of weeks he added a collections option to this app, incredible customer service!! It works perfect!

This app works perfectly, and it's very thorough. It blocks a wide variety of PO box entries and is fully configurable. The perfect solution to an otherwise annoying issue in Shopify. Their customer service is also very responsive and helpful. Highly recommended!!!
