How can I use Shipping Rates Calculator+ for delivery estimates in holidays?

The main goal of the app is to show the shipping rates on the cart page.

Shipping Rates Calculator+ displays your shipping rates exactly as they are configured in your Shopify admin. The app cannot be used to configure shipping rates, only to display them.

However, as Shopify provides delivery estimates when a real-time carrier is used, we also give the option to show those estimates.

What we do is display the estimates as Shopify gives them to us, and Shopify claims to give them to us as the carriers provide them. Regarding holidays, as far as we know, FedEx takes them into account, but some other carriers don't.

In order to mitigate the issue, there are a few things that you can do with our app.

To do so, go to the Real-time carriers section:

Add the desired cutoff days:

Finally, save the preferences:

Finally, save the preferences:

Explain the delivery estimations in the 'Shipping note'

To do so, go to the Visual styles → Shipping note section:

Change the note text to add this information or any additional information:

Finally, save the preferences:
