Bottled Saltwater

Has anyone use the packaged salt water that is supposed to be from the ocean comes in a 5 gallon jug?? My LFS says it great but I was looking for some other input.

I haven't used it but being the cheapskate that I am I can't justify buying water nor have I read about any benifits from using these products. As long as you can afford it there is nothing wrong with using it although I have heard that the calcium, alkilinity and magnesium levels are below the levels most hobbiests want to maintain so some additional suppliments may be needed if you are keeping corals but again I have no experience or testing to back this up.
