You can purchase a sweatshirt for $50 right here, and a portion of all proceeds will go toward funding organizations dedicated to promoting equality. Want more? The Ally Coalition is on tour with Fun., so if you're going to a show, you can check out food drives, raffles, photo booths, and even "soundcheck socials," where members of locally gay-straight alliances get to attend the soundcheck and meet the band.
Or, you can just hop on over to the The Ally Coalition to get more info. Easy peasy.
