December 1 was World AIDS Day and (RED) teamed up with Amazon to launch the third annual (RED) Shopathon. Every purchase made from this special curated collection of red products helps fight AIDS in Africa. And for every dollar spent during the Shopathon, Bank of America will donate $.30 to the Global Fight to End AIDS (up to $1.5 million). But rather than having us explain it all, (RED) created a hilarious star-studded PSA to break down all the details. Watch Bono, Julia Roberts, Kumail Nanjiani, Chrissy Teigen and Olivia Wilde help answer curious customers’ questions about the Shopathon in the video below. When one woman asks if (RED) products will interfere with her medications, Roberts nicely explains that, “(RED) products are safe to use in conjunction with your current medication.” (The questions just get weirder from there.) Check out a few screencaps from it by clicking on the thumbnails below, and watch the video below.
