The website PopNod has collaborated with more than 350 retailers and organizations, including Zappos and Best Buy, to make it possible for shoppers to get cash back on their purchases, and then donate a portion to charity. Shoppers can shop at their favorite stores online from within the site and then choose to donate between 0 to 100 percent of their cashback. "PopNod does all the hard work so shoppers can save money and help their favorite causes," says Stephanie David, co-founder of PopNod.
