Mighty PO Box Blocker

This platform plugin is very effective and we have had no issues with it what so ever. Would highly recommend if you are wanting to stop customers' on your website at the cart entering a PO Box into the delivery instructions (if you are unable to provide delivery to PO Boxes). It has saved us so much time.

It is a great app and I love it, It saved me more than 1000 USD in shipping to PO BOXES.
Some customers still placing orders with the PO BOX warning so it would be great if the app has a feature to send the mail notifications for these orders.
We can cancel those orders and ask customers to provide physical addresses.

If you're looking for a no-code way to warn your customers that you cannot ship/fulfill orders to PO Boxes, this app takes care of displaying a warning when entering the checkout and if you meet certain criteria, can also provide guidance to your customers during checkout as well, all without having to edit your theme or otherwise modify/edit any code.

This app is super simple and easy to install and control. Love the page with 3 simple options to toggle on/off at any time!
