Shipping calculator

Theme settings → Cart → Show shipping calculator (cart page only — not drawer).

A small form on the cart page lets customers enter Country / Province / Postal code to see live shipping rates before checkout.

Backend

Uses Shopify's /cart/shipping_rates.json endpoint. The rates returned are exactly what the customer would see at checkout — no estimates, real numbers from your shipping zones.

Tips

• Hide on stores with simple flat-rate shipping (calculator adds friction without value).
• Show on international stores where rates vary widely by country.
