We did most of our shoping in birm'ham too. Because we were hoping the luggage would arrive on the next flight
. But we still had to go out in ttown for a few other things at walmart/target/best buy (printer cable, bed rail, garbage can).
The walmart in Ttown is a 24 hour one on Skyland Drive. Went at 6:30am with husband, and it was really nice and quiet. Shelves were being restocked by the Army National Reserve (kidding, but there were hundreds of people restocking!).
