Two words: Double dipping. They do the same thing here in America. Anything to earn more money. In America they sold the Christmas episode on a seperate DVD for $10. I didn't buy it, but I found the Second Season at Best Buy for $5 more than anywhere else, but it included the Christmas episode. I wish they would release one DVD with everything instead of a bare bones edition, then a special edition, then a platinum edition, then a golden, edition then a diamond ecrusted ruby edition, and so on and so forth, into rediculousness.
