Please help! Quick questions about ATT pre-order :(

[Big.Mac.Daddy]

When I pre-ordered from ATT it said:

Your iPhone has been reserved and should arrive as soon as Sept 21st, 2012

Does this mean they have wiggle room to delay my iPhone 5 until a week from then since they put in the word "should"?

If it ends up being delayed at all I would rather just go to the store early in the morning and pick it up in person

Also when does ATT finally take the money out of my checking account? Right now there is a $1 pending transaction from them but when do they take out the full $286?

Edited the above post for clarification.

I just ordered a black 64GB from AT&T at 9:10am PST. All checkout pages through the ordering process state my phone will arrive on 9/21 and on my final receipt. Also stated twice that my card will be charged the day of shipment. Only a hold for the purchase amount is placed on the card now.

I ordered my black 32gb a bit after 1am and was charged the full amount and sent order confirmation (shipment processing) within the hour.
