Happify Delivery Rates by Zip

Create delivery zones from zip or postcode lists or prefixes and give each a flat rate with an optional free delivery threshold. Addresses outside every zone can be blocked with a clear message or fall back to your Shopify rates. Add rate rules by weight, order value, item count or product tag, same-day cut-off times and delivery time slots. Surcharges, a rate tester that explains every price, per-location zones and change history help you run it with confidence.
