Bundle of Holding
After Kickstarter my current gaming addiction is the excellent Bundle of holding. For a relatively small amount of money you can get a collection of games and supplements with proceeds going to charity; if you pay the level up price you can get additional books as well.
There have been numerous bundles so far covering all sorts of gaming worlds including; Traveller, Unknown Armies, Spirit of the Century, Stars Without Number, Feng Shui, plus old school gaming material as well.
The current bundle is Classic Deadlands the roleplaying game of the weird west, this is the pre Savage Worlds edition and if nothing else you can use the books with minor modifications to the new edition.
