Amazon currently has the Two-Disc 70th Anniversary Series DVD of the Wizard of Oz for only $8.49! This has a regular price of $20.98, and gets 4 out of 5 stars! You can also get the Blu-Ray version for only $10.49 marked down form $24.98!
Here is what one review had to say about it:
The DVD extras are a mind-boggling embarrassment of riches. The “Making Of” documentary hosted by the incomparable Angela Lansbury is worth the price of the DVD alone, but there’s so much more: an international poster gallery, interviews with cast members, deleted scenes, production stills, radio clips, etc, etc. There’s enough material to keep even the most casual viewer fascinated for hours, and a true Oz buff will be occupied for days!
If you only bought a DVD player to watch this one disc, it would well be worth the expense. Treat yourself, and fall in love with this classic film again … for the first time.
Keep in mind that Amazon can change their prices quickly, so this may not last long!
