The free things they have are special features and they usually only stay for a few months and then there is no trace of them. But if you keep on checking (every two days) The Clone Wars, all of the seasons on iTunes (US Store). Sometimes you can find free full HD Episodes. Like when Season 5 "Revival" (the first episode) was released after two days it was for free like 2 months, but know it costs 3 dollars in HD. Right now i found out that Season 5 "The Lawless" is free (07.05.2013). So if you keep checking you will find some of the episodes free, but just download them from YouTube or ulozto.cz unless you want to buy them.
You can get full episodes of the show a week after they air on Cartoonnetwork.com or Starwars.com, or you can buy the episode on iTunes a day after it airs for $2 (United States)
