Questions before installing

Frequently asked questions

How are the shipping estimates calculated?

The app asks Shopify for rates based on the current cart and the destination entered by the shopper. It does not create, replace, or change your shipping rates.

Do I need code or theme edits?

No. Enable the Cart Shipping Widget under App embeds in your Shopify theme, save, and test the cart. No Liquid edits are required.

Which countries and postal codes can shoppers use?

The widget shows destinations supported by your Shopify shipping setup. It asks for a province or state when Shopify needs one, and supports international destinations that your store already serves.

Does it store customer addresses or add heavy storefront code?

The app does not store customer addresses. The widget is designed to load only when a cart exists and to keep its storefront footprint small.

How does billing work?

The app uses Shopify Billing with a 14-day free trial, then costs $4.99 USD per month. Uninstalling or cancelling stops future renewals. The first paid month is covered by a 30-day first-charge guarantee.
