Ya know, salt is so dense. I would definitely look for a local source before incurring shipping charges for it. There is enough stuff we can't get locally, that I try to get what I can locally to save the $. WalMart, Costso, etc have pretty decent pricing on the 4# boxes, and you can find sea salt at any of your local health food stores. Your health food stores will often be willing to order you 50# bags of sea salt, too.
