I don't know if you all are already aware, but
con-or-bust is running an auction to raise funds for
their assistance project, which is now overseen by the Carl Brandon society.
In addition to being a supporter of their goal, I think that they also just have some really nifty stuff on offer, and thought you might be interested. ARCs from publishers, a NYCC guide signed by Stan Lee, some homemade knits and food, jewelry, DVDs, writing critiques and contract reviewing services, books you're unlikely to run across anywhere else (Tamil pulp??)... it's pretty great.
This is the tags page, so you can get an idea of what kinds of things and which authors are covered. It does still contain information for past auctions, but you can always jump to the "2012 auction" tag and start browsing.
Edited: Naturally, as soon as I hit 'post' I remembered something else. Bidding closes at 11:59 EST on Sunday, Feb 25, so you've got just under a week to look around and put your name down if something strikes your fancy.
