Polyhderon 36, 37, 38, and 39 - These seem to be from the late 80s. 99 cents each.
House of Illthrix - Apparently the first of three for the Avremier setting for OD&D. $2.99 and 29 pages.
No Sun for a Wicked Moon - Haven't heard much from Unbalanced Dice Games and apparently this is why, a 250 page mid level adventure for Labyrinth Lord where apparently the PCs go to the Moon. Even considering the rather spacious page format used, that's a big adventure (probably 70 regular pages). $6
Shrine of Ptallo - Possibly a comedy adventure (the description starts off with a half-naked man) for S&W for levels 3 to 5. 20 pages, $2.50
The Labyrinth of Cull the Chaotic - I got excited from the description, then saw it's 2 pages. 2 pages. The one page dungeon has to be the most obnoxious fad of the last 10 years. That and wearing pajamas as regular clothing. PWYW
The Sunken Temple of Chloren-Var - This seems to be system neutral, but with an old school style, strangely emphasizing lighting as a resource. 100 pages, $5.99
Men & Magic Compilation - Basically a reorganized OD&D, including the ranger, illusionist, and bard. Free!
Back to BasiX Issue 8 - B/X fanzine. $2, 29 pages. Highlights seem to be two comics and a Jaquays interview.
Echoes from Fomalhaut #04: Revenge of the Frogs - Latest PDF of Gabor Lux's excellent fanzine, including an adventure (from the title) and more. 44 pages, $6
Friday Enhanced Map 3-29-19 - The latest in what I think is a multi-part dungeon.
Mazith Random Cave Maker 2.5 - Program to generate maps of caves. PWYW.
