I got mine at like 5:03 online. I got a different seat in the beginning, but gambled and refreshed the page and got someone who didn't purchase their ticket in time. So sometimes it's just a waiting game. People rush in at 5 and scoop up all the good tickets, but not everyone buys them so they're re-released. It's just depends on your luck to get them. Through ticketmaster it's $300, but then each ticket has a $37.85 convenience charge attached, so for VIP seats it's $337.85. X.x
It's expensive, but I justify it by telling myself I get to see DBSK, SNSD, SuJu and Shinee all in one concert. And the last concert was like 4+ hours, so it's longer than most normal concerts I've been to.
