FP1 – Cart Shipping Calculator displays estimated shipping rates directly in the cart using the merchant’s existing Shopify shipping settings. Customers can select a destination and enter a Postal/ZIP code to see available shipping options and costs before checkout (final totals are confirmed at checkout). This helps merchants set clearer expectations and reduces checkout surprises. The widget sits neatly under the cart totals and is designed to fit cleanly into most cart layouts.

• Show in-cart shipping estimates using your existing shipping zones.
• Optional Geo-IP can preselect country for faster in-cart shipping estimates.
• Pick country and province/state (if needed). Enter Postal/ZIP to refresh rates.
• Uses your configured rates, including carrier-calculated rates when available.
• Works on cart page and cart drawer, and fits neatly under totals in most themes.
