Kobo has launched a 'Kobo 2012 Book Club' for new purchasers of the Kobo Touch eInk device. Membership entitles you to one free ebook a month (from a pre-determined list) throughout 2012. For more information check the Kobo Blog
Edit: Way to reward the early adopters, Kobo! The masses of black Friday zombies, pickled in pepper spray, desperately grasping for 'deals,' whether they need them or not, will surely purchase more books than the dedicated readers who have supported you hitherto. Good luck!
