MarginShip: Free Shipping

MarginShip creates a free-shipping rule that evaluates discounted cart subtotal, delivery cost, and existing discounts before applying a benefit. Set an optional order threshold, shipping-cost ratio, product or collection exclusions, and a configurable combined promotional cap. Cart messages are customizable in every plan. Growth simulates Shopify-returned rates; Scale adds decision diagnostics. The optional Impact report uses read-only order data to show confirmed MarginShip activity.
