The upstanding citizens at further soap have a special Earth Day promo that ends at 11:59p PST, so get to it... The concept behind the soap is pretty remarkable. After fueling a 1984 Mercedes with biofuel crafted from the waste of local restaurants, the founder's wife, Megan, recommended that they make something out of the byproduct.
Now further soap is popping up in the restaurants such as Mario Batali's Osteria Mozza and Pizzeria Mozza.Grab a bottle for Earth Day and they'll send you a free bottle and won't even charge for shipping. On Earth Day, everybody wins.
