Kmart has had these for a while now. It comes with copy of a G3.5 dvd for free over there. It appears to be a Kmart exclusive packaged like that.
THat's very odd if Kmart has this- it was street dated for today, not legal to sell. Of course, you CAN break street date, so maybe that's what they did...
After more pondering than it should have taken, I think I figured out why they chose those episodes- they all have the train, right? Except the first ones with Nightmare Moon, which I'm sure they put there as an introduction.
I was going to wait for the whole season, too, but I am not a patient person!
