To my knowledge they only air freight. I got a 37 gallon package and the freight for both shipemnts total came out to about $100. It is shipped in water so it weighs a bit more but there is very little die off that way. I feel your pain regarding the live rock around here. Its 5 or 6 bucks a pound and is pretty good if it has coralline growing on it anywhere. The tbs is covered with life sponges, barnacles, clams, corals and some pretty cool unidentified stuff. There's no comparison IMO. When you consider all the critters they send as part of the package. It actually worked out much cheaper than anything I had seen around. Their live sand is not aragonite but it too has lots of life. I waited over a year trying to find some good stuff around here and fianlly decided I couldn't do any worse than buying the local stuff and took the plunge. Now I wish I hadn't waited so long. Do a search on the board and check out some of the pics posted they are pretty representative. If you new some one else who wanted some rock it could even be cheaper. I'v been thining about taking some of my rock into one of the stores up there ans seeing how much they will give me for it since their barren stuff is usually 6 plus dollars a pound.
