Where can you buy White Linen Soap?

A few years back, my favorite Zest White Linen soap was no longer availabe. I called an 800 number at Proctor and Gamble and was told that the new Whitewater Fresh soap was exactly the same; just the name had been changed. I was able to find the Whiewater Fresh in limited quantities for awhile, but it also appears to have DISappeared from supermarket shelves. If anyone can explain why this is occurring, I would be most grateful. This is the one soap I have found that does a good job and doesn't irritate my skin. Thank you. Peg
