PS: Checkout Rules

Most stores pay one app to stop bad addresses, another to upsell at checkout, and a third to survey buyers. That is three bills and three scripts in one checkout. This app does all three. Block PO Box, Postfach and Packstation addresses in 10+ languages, require a house number, and restrict zip codes, countries, or order values. Add one-click upsell offers from a collection or your best sellers. Ask one question after purchase and save the answer to the order. Free setup support is included.
