Today the main Laclede product page brings me to this link:
 http://www.biotene.net/products/oralBalanceSpray.asp which is the same one I saw for a few minutes yesterday and says it is now available at  
www.drugstore.com.   However, when i click on the drugstore.com link, its not there.  But, I'm taking this to mean its available somewhere now anyway.  Just a matter of finding it or a store that can order it.
