Mine also said 09/16/2016, but also said on the order:
Thank you for your order. It is being processed and you will receive notification once it has shipped.
Your order includes one or more items on preorder or backorder. Your items will ship when available, provided that your account balance is current.
Mine said "deliver by 9/28" Ordered flat black 128 G 7Plus. Ordered it around 10:00AM EST.
I guess my question would be- would it just be better to wait in line at the store to get it on the 16th?
The only time I purchased a phone and stood in line was for the iPhone 4s. It was the day after launch day and there were 4 people ahead of me at the Apple store. I say go for it.
Mine did the same thing. Ordered the Rose Gold in 128GB at 3:24am EST. I sure hope that this changes, however if not I suppose another week won't be a deal breaker.
This may be a dumb question, but is it really arriving on the day it says it is? Mine says "deliver by the 16th" - But all the promos/ads say that they begin shipping on the 16th? Which is it?
