I've mailed CS within the U.S.. Just taped around the bottle-lid, zip-locked 
bottle in a bag, wrapped in bubble warp and boxed it. Never said anything about 
it. Bottles of liquid are shipped all the time. Got there without incident.
The only problem I see is that liquids are heavy, so shipping costs are high: 
it's almost cheaper to buy locally.
Be well,
Léna
