Also somewhat notable is Boot Hill 3rd Edition is up on DTPRG. I guess it was 2nd edition we played back in the day, I'm not sure how different 3rd is. Previous editions were clunky, but worked really well in play.
Delver's Keep - I think it's an adventure and not just maps. But at $9.99 and 28 pages, I'm not going to find out for sure.
Pyramid of the Lost King - I think this actually came out last week and I missed it. But big adventure for S&W. $8, 106 pages
Pyramid of the Lost King Extra - The Howling Dolmens - Add on for above. $1 and 3 pages.
The Graydeep Marches - This is interesting, a smallish setting and 3 short adventures from Peter Schweighofer who worked at West End Games and did a lot of work on Star Wars D6. Definitely on my "to buy" list. 34 pages and $6.99
Demi-Human Adventurers - Rules for playing race as class in S&W. Why you'd want to, and if you did, you couldn't just use the LL rules (or other B/X clone) for free. 75 cents, 9 pages.
Non-Human Player Codex for Early Era Fantasy Gaming - I'm not sure what it is, sounds like it's a reference guide to the non human classes in Labyrinth Lord. I'm not sure why you'd need this, much less pay $1.49 for it, nor do I think the B/X era is really "early", as it's basically 7 years after OD&D was first published and 3 since AD&D.
The OSR Chymist - This is a conversion of the Pathfinder alchemist class to OSR. I've read a number of Pathfinder novels and while most are dreadful, there's one series that features an alchemist that I quite enjoy and I wanted to convert that to OSR. PWYW, 15 pages.
Friday Enhanced Map 5-18-18 - Looks like a heart shaped cave. $1
Nod 34 - John Stater's excellent zine continue, this time focused on Persia. 117 pages and $3.99 If there's a better value (besides free stuff) in the OSR (or even gaming), I don't know it.
RPG Presents #32 - $2.49 and 13 pages for info on his fantasy campaign. Bleh, I'm starting to think I should ignore him like the Filbar guy.
