BookBub is a free email newsletter that keeps you updated about deeply discounted and free digital books. You choose the types of books you’d like to get notified about — with categories ranging from mysteries to cookbooks — and we send the best deals in those genres to your inbox.

BookBub doesn’t actually sell books. They simply alert you by email to fantastic limited-time offers that can be purchased from retailers like Amazon’s Kindle store, Barnes and Noble’s Nook store, Apple’s iBookstore, and others. Book publishers offer deals at these sites for promotional purposes, and BookBub staff works with them to determine the best ones to send to their subscribers.

I’ve been using BookBub for the past few months, and although the daily emails dot tend to clutter my inbox at times, the numbers of books that I have been able to download for free or under $2 is well worth the daily emails.  I would suggest that anyone with an e-reader sign up for this amazing service.
