50% off PDFs sale over at RPGNow. Best I can tell, it applies to everything that isn't free (free stuff is half of fee, which remarkably is still free!)
Save him from the Space Pirates in his dream, that gave him a choice of torture of a PDF sale. My players would have opted to have Joseph tortured, but at the DM I'd be going for the PDFs myself.
