Thanks for the responses. Healthy Bugger - thank you so much for your input. I would order from them again but their prices are a bit high for me since I need a large amount.
This company http://www.himalayansalt.com/bulk-salt-orders.php
was recommended by someone on the salt forum.
They have eating salt for $4.24 a pound and bath salt for only $2.75. I was planning to get 25lbs of each. I don't suppose you know anything about them do you?
