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!
