If you have an extra 2.99 you should really check out Skirmisher Games February Festivities Bundle. It includes 10 pdfs for various versions of D&D (3.5, Pathfinder, and 5E) as well as system neutral material. My favourite among them is Men & Monsters of Ethiopia... a 5E monster supplement that I reviewed here. Printable minis for the book are included in the bundle, as well as several other cool pdfs.
Skirmisher Game is a publisher I don't see many folks talking about, but in my experience they make some great books and the writers are super nice guys.
