I thought I posted this, but at least there is still several hours left.

Frog God Games has all their multi-adventure and gaming book bundles on sale right now for 75% off.
This means, you can get the entire Quests of Doom 4 series for $28.74 for 5E, PF1 or Swords & Wizardry. Many (if not all?) of which are available as FG modules now.


Lot's of other good stuff there too.
