Humble Fight for Racial Justice bundle: $30, 50 games (Steam keys, some also DRM-free), some ebooks, runs for a week, "100% of the proceeds from your bundle purchase go to help organizations fighting for racial justice through NAACP Legal Defense Fund, Race Forward, and The Bail Project via the
PayPal Giving Fund."
Baba Is You, Hyper Light Drifter, Football Manager 2020, Kerbal Space Program, Age of Wonders 3, Bioshock 1, Elite Dangerous, FTL, Spelunky, Super Time Force Ultra, System Shock Remastered & 2, etc. Not many complete / GotY editions, but still a nice selection for the price and considering it's for charity.

the Reddit GameDeals thread.
Edit: You also get a free month of Humble Choice if you’re a new subscriber. There are three levels of subscription, so I don’t know if that’s the $20 one or a lesser one.
