One tip, on the way down, buy a bottle of your favorite booze at the duty free shop. You can even buy online and they'll bring it to the plane. Prices are crazy down there!
Unlike some other USA airports where the deadline is 24-48 hours, note that orders for duty free at ATL seem to require seven day advance notice and AFAICT are prepaid and can't easily be cancelled (or just not picked up) for a credit.
Plan ahead......or just buy whatever the particular location has in stock on your travel day.
