It just depends on your location. The UPS by my office rang up the shipping before I could even finish filling out the invoice.
When I got to the section where you list contents, the guy helping me said, "Don't worry about that section. We don't really care."
It was a little anti-climatic. I had myself prepped to expect the 5th degree and... nothing. It couldn't have been easier.
Just make sure to pack them like eggs. I used tons of bubble wrap, tape, double bagged each bottle, bagged the entire lot in a construction grade garbage bag and taped again. Probably took my friend hours to unwrap.
If a bottle were to break, I imagine that's when the questioning would start. I don't think the carries would appreciate my IPAs and Stouts leaking all over the other packages.
