The World of Greyhawk (Folio) - To me, the best part of this was and is the map. I think it's always been up as PDF, but now has a POD option. Dunno if that's just for the folio or the map.
Frostbitten and Mutilated - More a sourcebook than adventure, for LotFP (kinda obvious from the title) and by Zak S. 144 pages and $12.99
One Page Dungeon Compendium: 2011 - $3, 70 pages
Quests of Doom 4: War of Shadows - This seems to be a sequel to some of the 412 Quest of Dooms 4 adventures, but I'm not sure which ones since they aren't numbered. $7.99 and 36 pages
Saving Sujeira's Soul - This is a historical adventure set in 1400s Portugal which interests me because my grandmother was Portuguese. 20 pages, $2.98, written for 3e but with conversion notes for OSR
Friday Enhanced Map 3-9-2018 - New named for his enhanced version of his friday freebie map. $1
RPGPundit Presents #23: Uncanny Creatures and Objects - 17 pages, $2.99
