The 'Estimated Shipping' module allows your customers to see your various shipping methods (and their costs) before having logged in. This can be particularly beneficial if you offer multiple shipping methods across multiple countries or shipping zones.
Where do I find it?
This is found on the basket/cart page, usually below the contents of the basket.
How does it work?
The user is prompted to select 'select your country', they are then shown all available delivery methods for that country. These are referred to as estimates as the delivery charge may change once the user has logged in (for example, they may be VAT exempt).
