Con or Bust is a cool program that helps fans of color attend SF/F conventions. You may or may not agree with their mission, but February is their big fundraising auction. And there are lots of cool goodies up for bid.
There are a ton of books of course - signed, ARCs, first editions, all sorts! - as well as crafty goods, critiques, and a bit of personal shopping. Most items are currently at the very affordable level, so I'd be sure to check it out and make a few bids if I were you.
