Drongo (Planet of Peril) - This is a adventure setting for White Star. 25 pages, $2.99, presumably inspired by Flash Gordon's brother Dash.
Fever-Dreaming Marlinko - This seems to be a city adventure, part sourcebook, part toolbox, part module and includes two new classes, including the robodwarf. 72 pages, $9.
FQ4 - In the Caravan Service - Mid level adventure from Adventures in Filbar, 27 pages, $3
The Alchemist's Task - Mini-dungeon for Swords & Wizardry from Creation's Edge games.
The Howling Mesa - Short 4 page adventure apparently about Jar Jar Binks. (No, not really, about gnolls). Pay What You want.
The Wizard of the White Hills - Short adventure from the Frugal Gm. 4 pages, Pay What You Want.
WishTaker - Not a lot of details about this, since the publisher didn't enable preview. But it's for 2nd-4th level characters who wake up after a night of drinking in a tavern with something odd happening. 24 pages and a whopping $6.99 (won't be buying this any time soon).
Outer Space Raiders Volume 2: Aliens, Creatures, & Foes - 8 pages of stuff for White Star. $1.49
Adventures Dark & Deep Deluxe Bundle - If you want to play with Joseph Bloch's houseruled 1e, well, then this is for you. $99.95 gets you hardback versions of the three books, as well as PDF copies.
Fever-Dreaming Marlinko Map Pack - Free maps for the book of the same name.
Patricia Smith Presents: Barbarian Anna - This is actually just stock art, but really one of the best pieces of old school style art I've seen, in the style of Frazetta. Pricey, though, at $10. I would love to use it in one of my classes (Amazon Warrior), but if you added up all the money from all the classes, it wouldn't quite add up to $10
Saga of the Splintered Realm Map Pack - Already mentioned this, but a bunch of free maps you can use.
