I just finished reading "I Work For Bigfoot", three Dresden short stories available as part of the Urban Fantasy Story Bundle.
The bundle includes ebooks by David Farland, Elizabeth Bear, Carole Nelson Douglas, Rhiannon Palle and Kevin J. Anderson. You can pay what you want, but if you cough up $14 or more, you also get bonus ebooks from Vicki Pettersson, P. N. Elrod, Peter J. Wacks, Michael A, Stackpole and - of course - Jim Butcher.
So... yeah. I basically paid $20 to get three new Dresden short stories, and a bunch of other stuff that looks interesting.
Totally worth it.
