As part of my interest in this topic, some years ago, I purchased on eBay the Laserdisc Boxed Set of The Godfather Trilogy (6 discs plus the bonus 7th disc: The Godfather Family - A Look Inside and booklet).
I never used it and have wanted to put it back on eBay to sell.
I am willing to sell it to any interested person here first who is willing to pay me the same $150 I paid plus about $25, shipping and handling from Los Angeles.
