This page is beyond long.  It's really mostly just an advertisement.  I'm not willing to pay what they're asking but some people might actually be interested, so I'm sharing this news.  Certainly right now we can't afford this salt, since my day care business is closed and my husband's business is fair but not booming like it usually is this time of year.  We have to be very careful how we spend, so I think we'll just stick with Himalayan salt (which we can buy at our local health food stores in amounts we can measure out ourselves).  We don't have to buy a big container or sack of it - - we can buy a tablespoon if that's all we wanted, which is nice.  Cost-wise there's no better way right now.

But this sounds interesting anyway.  Link above.
