I bought this Humble Bundle for one of my players as an early Christmas gift, I already bought a previous Pathfinder Humble Bundle which had no comics, but even more Rulebooks. Since I'm using Fantasy Grounds for my home games, I have also been buying up their in-app conversions of these books. Fantasy Grounds will reduce the price of their converted content by the cost of the full priced PDF files from Paizo.com so my $26 Humble Bundle has paid for itself 3 times over at this point.
$15 was a bargain for all this material. If I use the books, it'll likely only be the modules since the rules are SRDed.
The rules are on the SRD, if you plan to use rules from any book other than the Core Rulebook for any Pathfinder Society games however, you need to be able to prove you own the books you took abilities, feats, spells, items, classes or archetpes from, plus the artwork is really pretty, and paying for books ensures the hobby survives and artists and writers continue earning a living... plus it's a really good price for what you get for it, and of course, some of it goes to charity.
