Picked my 6+ up from UPS this morning, ordered from Apple app on 9/12 ~3:45am EDT, estimated Oct 1- Oct 6 delivery.
For those waiting, mine went to "Preparing to ship" on Thursday 9/18 and the actual cost (not the $1 hold) showed up as a pending charge on my Amex that same day. The phone "shipped" on Friday 9/19 but Amex shows the charge on 9/20. The phone sat in China Sat thru Sun, then made the slow trip to NJ. So it left China Friday, arrived on Wednesday, so like 4 business days for shipping.
My iPhone 5 came much quicker 2 years ago, but it was promised delivery on launch date, and it at my door that day. I think any delivery date after launch date is going into the normal UPS shipping queue/routing, so the packages may sit/take a less direct route if UPS has other packages with a higher priority.
