The Green World Rewards website allows Green World Rewards to automatically publish links from the major affiliate networks (Google Affiliate Network, LinkShare, and Commission Junction) so that its users can  get discounted prices from the major online retailers.  Users will soon be able to get an additional savings through a cash-back feature that rewards the user for each purchase.

At the same time, Green World Rewards and its users contributes to the environment by using a portion of its proceeds to purchase and retire carbon offsets - What a great idea!
