Methinks the "Bonus DVD" really is that additional content that can't be beat. I really hope that the DVD option remains for future games, that is, forever. It is the sole fact that brought me to buying games from Telltale, and I'd seriously reconsider if these games would never be part of my personal library.
As for the "sales" - I'm not always content with the sales cascades at the TTG store. I actually regret having pre-ordered Season 3 together with other stuff to reach free international shipping before March 31 - the 50% off S&M merchandise, starting
one day after the previous deal, would have been the far, far better option for me. Frankly, I would have emptied the store had I not ordered days before...
I'm really looking forward to TTG's new and fresh ideas about future "pre-order deals". After all, you can't do the same thing over and over again...
