Also, if you read any of my previous posts you’ll see that I squarely fall outside the category of “tech savvy” 
It is my lack of savvy that necessitates so many posts about basic things that are probably already understood by most.
And, believe it or not, where I live there is still a brick and mortar DVD rental business nearby that my wife and I visit all the time. It’s always busy too. So as long as they can tap the nostalgia of the last generation of people who grew up doing this they’ll probably stick around.
They also sell alcohol, which I’m sure helps their foot traffic.
