Peachtree is my very favourite place to get all my natural products. The couple who own the place are fantastically smart and nice (one of the owners is a nutritionist, actually) and it's easy to go there if you don't know how to start making the switch to "natural".
I mostly buy my biodegradable shampoo and conditioner from them, along with other soaps, but they also offer food stuffs (on top of vitamins, powders, etc.) including a great variety of gluten free snacks. They also make smoothies chock full of fruit and other boosters you might need. Oh and ladies, they ALSO sell the DIVA CUP (!) and bleach free, biodegradable "feminine napkins and tampons".
