I can’t believe I’m saying this, but Wal*Mart rules. Why? Because they’ve got a pretty sweet promo going on that will soon become obsolete since we’re posting the exclusives, but we’ll tell you about them anyway. So here’s the deal. When you purchase one of three special edition cover Transformers DVDs you’ll get a special access code that unlocks a behind-the-scenes video from the set of Transformers: Revenge of the Fallen every week. Or you can just use code: AllSpark62609. Heh. We have two of them available now for your viewing pleasure after the jump.
