What merchants praise
“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.”
What merchants complain about
“Does not stop people from checking out with a PO box. I was able to checkout with a PO box while testing it live on our site. It did nothing to stop me from checking out except add a free shipping method to the order that gave me a warning to enter a PO box. My default shipping still remained as an available option and I was able to check out with that option. But it did not do what it says it will do which was to stop people from being able to enter a PO Box. Uninstalled this app right away.”
