Shipping Wine from Italy to US (Cali)

[RJonesUSC]

Hello,

I'm interested in shipping wine from Italy into the US. I have some family on vacation in Italy right now and they would like to send some of the wine they've already purchased to the US, California specifically. What are the legalities of doing this? If it is legal, how much does something like this cost per case and who would you use to do the shipping?

Thanks in advance.
