As a stupid american consumer - delivery means on the damn truck that is on my way to my house.

As per UPS: http://www.ups.com/content/us/en/tracking/tracking/description.html

"In transit":  Your shipment is moving within the UPS network and should be delivered on the scheduled delivery date.
"Out for delivery": The shipment has reached the local UPS facility responsible for delivery and has been dispatched to a UPS driver.


Also "package delivery date" means when a package delivered not shipped.
