The newest social shopping site has a charitable spin! Mulu.me is a Pinterest-like pinboard where users can curate wish lists, and if a visitor purchases a product through the site, Mulu splits any affiliate revenue with the user who posted it. Posters can either donate the money to one of 38 popular charities, or have it paid directly to themselves via PayPal. "Users can follow their friends, style arbitors, tastemakers and celebrities like Zooey Deschanel and her Hello Giggles pals, Busy Phillips and Michael Kors," Mulu founder and CEO Amaryllis Fox told InStyle.com of the growing celebrity following. "It's pretty empowering to be able to support a clean water project in Sudan with your killer taste in shoes." Check out mulu.me to sign up!
