here is the shipping cost in euros/BTC to TX from DHL (guess prices are the same whole U.S.)
up to 2 kg (3-4 bottles) 15,90 ~1.59 BTC
" " 5 kg (9-10 bottles) 35,00 ~3.00 BTC
" " 10 kg (19-20 bottles) 45,00 ~4.50 BTC
" " 20 kg (39-40 bottles) 65,00 ~6.50 BTC
" " 31,5 kg (62-63 bottles) 85,00 ~8.50 BTC
so adds +0.137 BTC each bottle, if you order maximum of 60 bottles
may there are cheaper cargo agents.. but i doubt
