I don't believe in signing at night. One more signature costs twice as much, and it's basically fake. You'd better have someone who knows how to go to Korea to help you. In South Korea, the average video store should sell the most genuine albums like China. Usually put up posters and buy pirated ones. But I heard from my classmates that you can ask them to sign it and they will send it back to you, but it seems that the cost of signing it is very high.
