Free shipping without losing margin

MarginShip evaluates the real promotional cost of each order before making the cheapest delivery option free.

Install MarginShip from its Shopify App Store listing, then open it from Shopify Admin.

• Discount-aware. Existing product and order discounts reduce the remaining promotional budget.
• Margin-aware. Shipping is granted only when the complete benefit remains inside the configured cap.
• Multi-shipment ready. Only the cheapest option in each delivery group receives the discount.
