I think the combo pack is to entice DVD-only people to consider upgrading their player. Possibly it also encourages retailers to stock it, because then they don't have to choose(guess) amounts needed of each format and make shelf-room for both.I guess I was trying to figure out what the benefit is for the studio/distributor. I guess they determined people are more likely to purchase a bluray if you add a DVD with it? Because it's not like what I saw was ridiculously higher than just a bluray. I personally would rip the added DVD and add it to my plex collection since I don't have a bluray reader for my PC. Yet.
I never understood why they did that, other than pushing up the price. They never sold VHSes and DVDs together back in the day, for instance.
