Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featurePO Box Blocker Pro checks each shipping address at checkout and blocks addresses you can't deliver to before the order is placed. Block PO boxes, parcel lockers, locked bags, private bags and APO/FPO addresses, or restrict delivery by country, state, city or postal code. Allow chosen products, variants or collections to bypass the rules, set a custom checkout message, and test any address before going live.
Some carriers (e.g. Fedex) charge extra fees or refuse delivery to PO Boxes. SafeShip validates customer addresses at checkout and blocks orders with PO Box addresses before payment. This prevents failed deliveries, avoids carrier surcharges, and saves you from manually reviewing orders. Customers see a clear message explaining why their address cannot be used, reducing support requests.
