Frog God is running a sale through Sunday. these prices are hard to beat, and impossible to beat on the Razor Coast Bundle (one day I will run this) - a $180 value for $72!
Most is available for Swords and Wizardry (Fire as She Bears is Pathfinder only.)
My highlights would be:
The Rappan Athuk add ons for 2 bucks a pop.
Cyclopian Deeps Chapters 1 and 2 for a buck a piece.
The $100 Grab Bag for $60 (each bag contains a minimum of $300 in retail product.)
The Razor Coast Bundle I mentioned above.
Stoneheart Valley for $20.
