Netflix DVD is solving a different problem. The issue with Redbox or streaming services is they frequently have absolutely nothing I want to watch. I tend to go to the movies enough to have seen any new releases that I had any interest in. However, with a vastly larger selection I can load up on classics or random recommendations. It might not be what I was in the mood for, but it will be good.
In the years before streaming netflix, I often did Redbox. Pick up a DVD on the way home form work on Friday. Return is Saturday when I go out shopping.
Do it twice a month, spend $2 (or $3 when they raised the price).
Netflix was 9.99 or more, and you basically had to watch 5 or 6 DVDs a month to "get your monies worth". So I often found myself watching a DVD when I didn't want to because I had already paid it, so I could send it back and get the DVD I actually wanted but didn't get because it was out of stock.
