Hello @Joshua14 ,
You can provide FedEx Priority Overnight service for orders placed on Friday using FedEx Rates, Labels and Tracking app (see the image attached).
This FedEx Shipping app provides you an option to enable/disable the Saturday delivery service. So, once your customer places an order on Friday, the Priority Overnight service will be displayed for the eligible orders. You have to enable the Saturday Delivery service in your FedEx account.
Joshua, as far as I am aware, there is Saturday delivery available for Priority Overnight shipments. Here is the FedEx link which says that. In fact, FedEx provides Saturday shipping support for the following services :
- 2 Day
- Priority Overnight
- International Priority
- Ground Home Delivery
The only thing that you need to find is a solution that shows only Priority Overnight if you are shipping on a Friday. With a little tweak in the Multi Carrier Shipping label app, you can definitely get this.
