Its likely that store orders were not processed until close of business and thats why the store quoted a longer delay.
I would never order in a store when there is an ordering website. Also, why did you wait so long to order. You could have got up at 8AM ordered online from home, and you'd get a phone on Friday.
The general concensus online was that ATT orders after about 4 PM on Friday would not arrive by 10/14.
