Paperback writer, a blog by Lynn Viehl often holds give aways and various contests, often having her own, signed books as prizes.
One she had recently was called "Last Call" giveaway. It's a good read about how she has been trying to get rid of a large number of professionally printed bookmarks (big mistake) since she started selling novels and she's down to the last one. That, along with the novel of the winner's choice are the prize.
Here's the winning announcement... me, me, me... hahah...
As I said in an earlier musing, I attract books. This still seems to be the case. :-)
