Currently even if a parcel will be delivered to a customer on a Saturday or Sunday the date estimation (when using Premium or Priority naming) does not reflect this.

For example Royal Mail Tracked 24 delivers 7 days a week. The dates shown to the customers ignore this and shows it being a slower service. I imagine other services are the same.

Either allow Support to configure the "delivery days" for individual services or add a feature to the Courier Module to mark what days the service delivers on. Note this is not a request to allow dispatch on a weekend but rather a calculation of days to show on the website for when customers can expect delivery.

This is important as retailers are up against the might of Prime and next day so competing on speed of delivery is key. Customers are getting a better service that we able to communicate to them. Showing this will increase revenue and sales.
