PS: Checkout Rules

PS: Checkout Rules is positioned as an all-in-one checkout utility for merchants who want to reduce failed deliveries, increase order value, and collect post-purchase feedback. It combines address validation and blocking features with checkout upsells and a simple survey flow, which can help streamline multiple checkout-related tasks into one app. The app appears especially useful for stores that need to block PO Box, Postfach, and Packstation addresses, enforce house number and shipping restrictions, and offer one-click upsells from collections or best sellers. Free setup support is included, which may make implementation easier for merchants who want a more hands-on onboarding experience.
