I found this complete series DVD set at Half Price Books. I heard nothing about this being released and have never seen it until today! So happy!

I saw it on Amazon a few months ago. It looks it was released on October 2, 2018.

It's only $34.99 on Amazon. How much did you pay?

One of the best-loved and most acclaimed TV comedies of all time starred Mary Tyler Moore as Mary Richards, a single woman in her thirties who worked as an associate producer of a news program at a Minneapolis TV station where she found a surrogate family in her quirky batch of co-workers. The series, which aired from 1970-77 and led to the spin-offs "Rhoda," "Phyllis," and "Lou Grant," also starred Ed Asner, Valerie Harper, Ted Knight, Cloris Leachman, Gavin MacLeod, and Betty White. 168 episodes on 22 discs. 71 1/2 hrs. Standard; Soundtrack: English Dolby Digital mono; Subtitles: English (SDH), Spanish.

I can't believe I didn't know about this all these years! What a great surprise. I paid $25. There's also another box set from Australia!
