Nope, never heard of them before, but they do seem to have two products that appear to be potentially useful in the OSR-verse.
The first is Nightmare of Tarring Hollow, a low level OSR adventure. It's short at about a dozen pages.
The second is Classic Lairs, which is an assortment of small dungeons and lairs.
Do i think either one is worth the suggested $9.99 price?
Lets see, I could get Astonishing Swordsmen & Sorcerers of Hyperborea for just a penny more.
I put these two in the "try before you buy category", although Classic Lairs certainly has more potential for use.
