Apparently, according to Chris, they sell it in Boots the chemist. I have never seen it, and i'm certainly not lugging a 5litre drum back home, on a regular basis. Anyway plastic is not good.
I wish they would not use plastic so much ie shrinkwrap vegetables,etc, is that really necessary. When i had a mineral test after doing a herbal detox awhile back, i showed high for cadnium. Probably leached from plastic into my food or drink.
