That was me - my Mom bought the whole set used off eBay. She got it for next to nothing, but the time spent with my daughter and the discussions it triggered were priceless. She could have spent ten times more and it would still have been worth it!It was, along with CHiP's, Emergency 51, Muppet show, Happy Day's, & PBS Nova specials were what I recall as the "after dinner" & "before bedtime" week night shows back in K-6th years of the 70's.
There is another user on here that I recall banter with them about M*A*S*H specifically and "she" talked of how they got the dvd set of the entire history and watched it with there kids a couple episodes a night --- all the way thru....
Don't remember if they bought it new or checked it out from library or a recycled books store....
That's was not the only TV show we talked about either.....
(Thinks aloud)"I'd bet the search function will find it as I wrote the title here as it did back then....." Hmmmmm
....[edit: Found it! Was in a private convo. They got the entire set as a present. There story was cute how they made it family time and stretches out over several years watching all 11 seasons.
I gotta admit i'm itchin' to see the original movie. I never got to see it all the way through.]
