These are companies where you can buy a product and that the money goes directly towards helping someone in an impoverished 3rd world country. 

Toms Shoes pretty much needs no introduction. For every pair of shoes you buy they give one pair to a child in need in another part of the world. The greatest for profit socially conscience organization of this generation in my opinion.  

100 Cameras is an organization that gives children in 3rd world countries a camera so they can document their day to day lives. Then you can purchase pictures that the child has taken and all the proceeds go to helping that child with living expenses.
