Hawaii Five-0 Classic Complete set listed but unavailable for purchase

This boxset has been listed on iTunes for over a year and it is still unavailable for purchase. I would consider purchasing individual seasons and eventually own them all, but all seasons are not available. The boxset seems to be the only way to get them all. The rating of the boxset is at 2 stars because people have been voting it down because it is never available for purchase and no one at itunes seems aware.

My point is this: If a show is not to be sold - don't list it. If you list it? Please put a price on it so we can purchase it.
