I used to work for Fedex. UPS absolutely has a hold until 9/21 delivery. They can and will hold anything at the hub until they are supposed to deliver it. They will not put it out for sorting until that delivery day.
Same here. However, my second phone says by 3:00 PM (or end of the day for residential deliveries). One of my phones came from China, the other from TN. ???
They would only save on shipment costs to the USA, and Apple is now a world consumer supplier.
There are MANY OTHER countries Apple is actually saving more on shipment costs for, due to being centrally located in China, such as europe, australia, africa......
That does not mean the savings in shipment cost is being reflected in the pricing of those regions, as has been obviously stated by those that pay much more for Apple products there than we do here in the USA, however it does mean they get their stuff sooner than we get ours.
