Best Free Paizo stuff?

[atemu1234]

So I just got an account at the paizo online store thing, and noticed there's a bunch of stuff that's free to download... is there anything particularly good for free on there, specific to pathfinder/starfinder/d20 stuff in general?

I don't have an account there, but maybe now I want to.

Since Pathfinder has an srd maybe the base books are free or cheap?
