1) Is this the same box set as the one on amazon?
If yes, why the price discrepancy?
on here, the link tweeted by Vertical, they even go for 100... ?
2) , but..... do they ship worldwide? I know amazon does, but does this too?

even though I'm still in the beginning stages of learning Japanese, I'm thinking of buying these: they could serve as a nice goal and gift for myself.
I was thinking that I could wait and buy them when I eventually travel to Japan, in the next 2 years, but I'll do that with the Blurays, these are limited edition so my FOMO is turning on.
Calculating the customs costs is gonna be a nightmare...
