Why does History Channel show more show listed for season 5, and they are not on iTunes?

Why is it 35$ for 7 episodes? Its cheaper to buy each one individually. I tried looking up the season list and could not find any future episodes so it appears this is the complete season. Any one know?

This series helps us all to take a look at what the human race has believed to be true--from a fresh perspective. It also does a good job at educating each of us about the various similarities between our world religions and beliefs as a human species. Every day new information emerges from satellite photos of the Earth and Mars. All it takes to change a legend into a fact of history is for enough of us to examine the evidence for ourselves and to keep an open mind to this trend. It will bring us all closer to one another and hopefully bring an end to all this war and hate.

These investigations done with the knowledge that it may be groundbreaking still required courage if not tremendous courage. Imagine coming to grips with the reality that our past is based upon the written records and that it has a slight twist to it: that some of our texts may infact prove to be true. Puma Punku has H blocks that look to be molded as if melted and formed in identical blocks like childs toys weighing tons. Stone does melt lower than steel however no one knew this thousands of years ago to have melted the blocks or the steel tools needed to refine the blocks. It is completly obvious to anyone looking at Puma Punku that it is of the gods period end of story no oposing argument.

Watch, listen, and gain insight into the real world around us. One thing about this the believer needs to understand; it is not important nor relevant that governments officially acknowledge connections to these theories; what is important is that this information opens minds and is in it's own right relevant. There will never be an officially "you got us, we covered it up" statement, nor does there need to be. The believer needs to understand that it is important what they know as true and not what sheep who follow aimlessly think or feel about this subject, fore they are irrelevant. Get on my level.
