Here's an easy way to save a few trees in the long run....Buy bar soap without the box!
Lately I've been buying these round, 100% vegetable oil soaps made by Sappo Hill at my local Whole Foods Market. They don't even have a label other than a tiny bar code - it's just good-old-fashioned soap without the waste.
Take a look on Etsy and you'll find plenty of homemade soap vendors:
I'm itching to try these beautiful, organic soaps from Mirasol Farm in River Falls, WI. If I ordered a bunch, I bet they would be nice enough to send the soaps all in one big box instead of individually packaged. :)
If you are looking to stock up, consider Joan's Gardens cold-process soap made with herbs and essential oils - your choice of 6 soaps for $20 bucks.
Soothing Suds cold-process soaps are a little more expensive but you get 10% off when you order 5 or more at a time.
Or how about a 2# soap log that you can cut into bars yourself? Artifact Soapworks makes them in a variety of scents and colors.
Do you have a favorite bar soap without any packaging?
