Marketplace
From the Humble Store as part of their end of summer sale, a promotion for Daedalic Entertainment Games:
Buy 3 titles get 80% off
Buy 4 titles get 83% off
Buy 5 titles get 85% off
Don't know when it ends but I'm guessing either 4:00 AM AEST Wednesday 8th September (that's when the new deals kick in) and it has been on their store page since yesterday.

From what I skimmed on Steam and the videos I watched, those were the titles that appealed to me (along the lines of Grim Fandango, Monkey Island, etc).
