It depends on the time of day that the post office in Alabama gets it. If you deposit it in the post office @ 3:00 in the afternoon, it will arrive in Texas by 6:00pm the following day. And be delivered to the postal zip code by 6:00am the following day. Time of day is everything. If you deposit it in the post office @ 7:00pm, it will take a minimum of 1 extra day to arrive at it's destination.
