PF1/Comic/AP Humble Bundle
For the next 20 days, there is a new PF1 humble bundle for $15. You can get a bunch of the basic PF1 books, adventures and comics.
Adventures are:
Crypt of the Everflame
Masks of the Living God
City of Golden Death
If you need a re-roll, it has a folio.
The books are:
CRB, APG, ACG, Utimate Magic/Campaign/Combat/Equipment, Bestiary 1-3, Strategy Guide, Gamemastery Guide
+ Beginner Box
Anyway...any way you slice it (even if you don't necessarily need the books), it is an efficient way to get older content or PF comics.
