To begin with, purchasing anything at an Apple store (physical or online) through Apple Pay between now and December 6th will donate $1 toward (RED), up to a maximum of $1 million. Bank of America will match those donations if you buy using one of its cards. You can also buy an album from The Killers (Don't Waste Your Wishes) on iTunes with all US proceeds heading to the fund. Beyond this, in-app purchases in 20 high-profile iOS games (including Angry Birds 2, Clash of Clans and PewDiePie's Tuber Simulator) will contribute to the anti-AIDS campaign through December 7th.

These individual efforts may seem like drops in the bucket, but Apple has historically been one of Product (RED)'s strongest contributors -- it had raised $65 million by 2013. And while a bona fide cure is still years away, the United Nations now believes that you could realistically see the end of AIDS by 2030. You may only make a small difference by yourself, but the combined effort adds up.
