The Avengers Confidential BD at BB also had the movie cash (along with a bunch of Spider-Man discs with the same sticker).
As a warning: the movie cash code and instructions are on the back of the sticker. It comes off the slipcovers fairly easy...just don't throw it away!
I've got Enterprise S4 on preorder. I'm not sweating the price; they've historically lowered the price to match BB or Amazon by the end of release day. Also going in for Avengers Confidential at BB.
Thanks, as always, Mike!
