I just found some nice promotion codes for the online store Planetshoes.com that will get you 10% or 12% off your order. I’m guessing there is a different minimum spent amount for the two discounts, but unfortunately I wasn’t able to find more information about it. So just try to use one and if it doesn’t work try the other one ;). If you purchase a pair of boots I also found another online code that will get you a sweet 20% off.
Planetshoes supports a bunch of eco friendly organizations and is part of the 1% for the Planet program, which means they donate 1% of their profit on sales of their own brand to approved environmental organizations. They sell all sorts of footwear for men, women and kids at affordable prices.
