Con or Bust

Con or Bust provides financial assistance to people of color to go to conventions. Which is something you want to help with anyway, but also: they raise funds by auctioning stuff and the auction is open, with loads of books, including ARCs and rare editions and signed copies, and bundles, tuckerizations, a bookmark that says "Social Justice Warrior," a chunk of Farscape's Moya, story critiques from Alyssa Wong, Yoon Ha Lee and others, project management time, and other coruscating desiderata.
