for some reason itunes or hasbro decided to chop up the season in half-volume sets. episodes 1-13 would be volume one, episodes 14-26 are volume two. they did this for both season one and two. season three being 13 episodes as is will only have one volume obviously, and that could be why they decided to chop them up (future seasons being likely 13 episodes)
the price for both halves of a season appears to be the same price though. first half is 20.99, second is 29.99 (roughly $50 for a whole season).
