All FedEx Priority Overnight labels for your shipments will indicate "Saturday" above the words Priority Overnight. These labels provide next day delivery Monday - Thursday, as well as ensure that packages shipped on Friday will arrive on Saturday.
FedEx does not pick up or deliver on Sunday. Shipments tendered on Saturday will deliver Monday. Shipments tendered to FedEx on Sunday will deliver Tuesday.
If your labels do not indicate “Saturday” it is because Saturday delivery is not available for the address on the label. If you ship this cooler on a Friday it will deliver on Monday.
