Much of that imported stuff will be food, bananas, fresh fruit and veggies from Chile and other S. American countries, time will be of the essence to unload. People want fresh products all year long. If you have a load of fresh grapes and stone-fruit from Chile, Bananas from Ecuador, they can't sit out in the harbor very long. Prices in the stores will shoot up, anything spoiled will bring a lawsuit from the insurance companies.
The 99 Cent store crap will wait til spring, might make a little bit of a shortfall in the holiday season.
