Humble Bundle offers downloads of its Humble Pathfinder RPG Book Bundle for whatever you want to pay. If you spend the bare minimum of $1, you'll get access to 11 books, including the beginner box, core rulebook, GM guide, and bestiary. For comparison, you'd pay about $14 for most PDFs elsewhere. If you opt to pay more than the average (currently $8), you'll receive nine more books, including the advanced player's guide, codices, and adventure modules. Pay $15 or more to unlock 13 more books, expanding items, monsters, and lore. Finally, pay $18 or more to unlock 18 more books, detailing races, locations, and more. Deal ends March 6.
