Today we observe World AIDS Day, a global health campaign to bring more attention to the virus that has claimed more than 35 million lives since it was identified in 1984. With the red costumes, bake sales and the annual Red Run, we’re given a number of opportunities to assist in the fundraising efforts, and even if this Friday finds you glued to your computer screen, you can make a contribution with just one easy click. From Amazon to 3.1 Phillip Lim, some of our favorite brands have partnered with (RED), the nonprofit organization founded more than a decade ago to help fight AIDS, particularly in Africa where nearly 70 percent of people living with HIV worldwide are concentrated. Here, the simple ways your shopping habit will do good during this season of giving.
