Amazon.com Tokyo Dome $79.78 USD
Amazon.JP Tokyo Dome 6390 yen
But even so I'd still get Budokan or London instead. Personal preference but I prefer those shows vs the Dome. And most of the time those both can be found for ~$20 a pop so both of those blu-rays can be bought for half the price as Tokyo Dome.
Don't know where Wyzzlex is located, but US Amazon keeps sending me recommendations for it, so I checked. Here It's sold by a 3rd party and fulfilled by Amazon for $80.
It's on the U.S. Amazon....
