Finely tune your shipping rates

Show, hide, or block shipping rates at checkout based on your customer's postcode. No code required.
PostRules lets merchants create rules that filter shipping rates at checkout based on a customer's postcode. Show mode restricts postcodes to specific shipping methods. E.g. Only show rural delivery options to rural postcodes or block mode prevents customers placing orders from postcodes you can't deliver to. Everything is configured within the app's dashboard.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows PostRules on a store, it is there.
