If you like the Gentle Cleansing Castile and don't want them to discontinue it, please send PSF an email expressing your concerns. I did, and got this reply from them: (I complained about the GCC being discontinued, and they offered to send me a sample of the new replacement bar, which I accepted in a second email, and also asked them for a sample of the Gentle Foaming cleanser as well, which they are sending). Maybe if enough of us complain, they'll bring it back.

Thank you again for your email. Yes I will be happy to send you a sample
of the PSFpro Gentle Foaming Cleanser as well. Thanks again for your
comments & your inquiry. Our customers opinions are very important to us
and we really do take them into account.
