I don't think it will cost that much for you, but check it yourself anyway.
I can reccomend you some japanese seller on ebay from whom I often buying brand new limited editions, but I think this box will cost you pretty much.
You can try to buy it from amazon.co.jp

they don't have their copies left, but some people selling brand new there, I'm just not sure if you will need middleman or Amazon will ship it to you
