Comic book fans looking to get into the Barnes & Noble vs. Amazon war, take note, the former is offering $30 off both the 8GB and 16GB versions of the Nook Tablet when you purchase two digital Avengers comics. If you're really just a fan of saving money (and who isn't?) you can pick up the two cheapest qualifying comics — "New Avengers, Volume 2: The Sentry" and "Dark Avengers, Volume 2: Molecule Man" — for just under $14, meaning you'll be saving $16 on the tablets themselves, which cost $199 for 8GB and $249 for 16GB. To get the deal, just visit Barnes & Nobel's website and purchase two of the qualifying comics on your account; up to two days later you'll be emailed a coupon code that you can use in-store or online to get the discount. If you're considering picking up the Nook Tablet, be sure to read our review, and keep in mind that the offer runs through May 6th — just enough time for you think before making a hasty decision.
