Good went to the port closest to their intended customers. If the majority went to New York and Boston and Philadelphia then that's where the consumers were.
You clearly do not understand what was going on. "Coastal Packet." Do you speak it?
Which is a further indication that the quantity of imported goods demanded by the South was minute by comparison with the North. If there wasn't enough to justify bringing the goods directly to Charleston or New Orleans the coastal packets worked just fine. And that's what I've been saying all along; there was little demand for imports in the southern states.
