Groupon, Groop Dealz, Woot, Zulily and many online retailers of this sort send you e-mail notifications about great deals based on your preferences and interests. Goodreads is now offering this same service for e-books. Once you sign-up, Goodreads will notify you of discounted e-books based on your Goodreads account profile (authors you follow, books on your want to read list, books you’ve read, genres you like, etc.) This new Goodreads feature is a great way to satisfy your reading cravings without going into debt. Check out the Goodreads Blog for more information.
