The new bundles are:
1) Weird Fiction
2) Multimedia Fantasy Music, which includes several music albums. With this bundle, with less than 13 days left, they're unlocking new ebooks and "B-sides" to the albums for every 1000 bundle purchases. If something's unlocked, everyone who bought the bundle gets those as well.
I'm trying to cut down on my purchases until I have time to READ some of the ebooks I've bought, but both these bundles have books/music that interest me so my pile may be getting larger again.
