These sets are simply WAY too much money. I am glad I am not a Sopranos fan enough to own the sets, even at $80 (which is the lowest anyone can sell it for), thats $6.15 an episode for the 13 episodes. Compare that to any other TV set generally going for a maximum of lets say $50 at mostly 24 episodes thats $2 an episode. Some sets are just too much.
If you buy around the release date or from eBay a few months after the release, you can usually get Sopranos sets for around $60 each, which is at cost, I believe.
