M J Rose draws attention to a chance to win signed copies of 150 novels by "some of the best and biggest thriller writers in the business" in this post: Buzz, Balls & Hype : WIN A THRILLER LOVERS LIBRARY OF 150 TITLES.
All you have to do, apparently, is to go to the 150Thrillers website and sign up for their free newsletter, before 15 February. This automatically enters you into the draw. I’ve signed up, but I kind of hope I don’t win anything, as I’ve got far too much to read as it is. (150Thriller website is now in the sidebar under "crime fiction sites".)
