Absinthe is legal and available in the US. Real absinthe too, not just the imitation stuff (although you can get that too, if that's what you're into). It's expensive, but it can be obtained. On a related note, that stuff is AMAZING.
Well there is a couple things but i dunno if you would be interested in them:
1. Booze like absinth or a really good bottle of scotch from scotlad that is hard to come by in north america
2. German beer stein ( those crazy german beer mugs with a lid) , i think they are pretty sick
3. European millitary stuff : i'm not talking about about guns, i mean equipment or clothing that is pretty cheap, like for example a real bundeswehr army jacket or shit like that if you are into that kind of stuff.
Everythign else is pretty much cheaper here and easy to get.
