Odd bit of trivia

 So I happened to be on amazon today, and noticed that the cheapest price for "The Music Man" on DVD (new) was $95.  Used (well, a reasonable used copy) was about $40.  Ebay was $50.   When did the prices skyrocket?  Why is it so expensive?  

And I'm now thanking my impulse buy: I got "The Music Man", "Seven Brides for Seven Brothers" and "Meet Me in St. Louis" in a 3 pack for about $13, if I remember right.  Yea impulse buy!
