[Pieces_of_SEVEN]

Thinking about ordering from here for the first time, but for some of the items I'm ordering, it says "This item is embargoed item." and I'm not sure what that means.

I live on the east coast of the US, and I've never had to pay customs charges for ANYTHING and I've ordered from YA, CDJ, and amazon.co.jp. Ranging from small things to huge things like the Rock 'n' Roll Circus box set or the Love songs/ayu-mi-x 7 vinyl sets.

So what does this mean, and should I be concerned?

Thanks!
