Saturday Delivery

Some shipping carriers support delivering packages on Saturday. Often this is a special service option that comes with an additional cost.

To specify a shipment as Saturday delivery set the saturday_delivery parameter to true. You will also need to set the ship_date parameter to a date prior to Saturday. The estimated delivery date needs to be near Saturday in order for the shipment to qualify for Saturday delivery. Often it is only available if the package would normally be delivered on Monday.
