There are two Humble Bundles active for Pathfinder at the moment.
For those who don’t know Humble Bundle - it is based on a ‘Pay What You Want’ policy but you can unlock more stuff if you pay more.
So in this case you can get quite a lot of books (PDFs) for about 20 bucks.
The first one will expire in a few days and contains many rulebooks:

The other has just started and contains some comics:

Remember when one of Pathfinder’s key selling points was that everything is contained in just one book?

Went to make a new post about this and the forum helpfully suggested this thread 
Humble Bundle are running a new Pathfinder feature (2017!).
Tons of stuff available (e.g. buy the rulebook for just $1)
Well worth a look at least (and part/all of your purchase can go to a charity)
Wanted to make that post here, too. But sadly nobody rly reacted to the first one. Except for H of course
