Domain Building - Pretty much what it sounds like. Free and definitely worth a look.
Human Race as Class for Old School Essentials - Okay, sort of funny. 2 pages, PWYW.
The Children of the Gods: The Classical Witch for Basic Era Games - Seems to be for Blueholme. $2.99 and 84 pages.
Alarms & Journeys - An OSR zine, presumably no relation to the similarly (if more British) named classic zine of the 70s. 56 pages, $2.
Friday Enhanced Map 9-6-19 - At first glance, I thought perhaps it was the intestines of a giant or something. But it's a weird looking cavern. $2.
