My wife and I used to rent videos from a local mom&pop store (which we really enjoyed for the social aspect of talking about what we liked and hearing their suggestions), but Blockbuster moved into the neighborhood not with one, but with two outlets within walking distance - kind of like the way Char Yucks put locally-owned coffee houses out of business, deliberately and with malice aforethought. They didn't last too long after that.
I always feel conflicted about purchases from Amazon, but then, times change. I am nostalgic for the way things were (I mean, those algorithms that Amazon and Netflix use to make suggestions are terribly sucky) and I miss the salespeople who know what they're talking about when they offer suggestions (where I'm from, salespeople get snooty if you don't take their advice seriously). I finally told myself that, just as I greatly appreciate the new technology that finally allowed the pick-ups on harps, and other acoustic instruments, to reproduce their sound faithfully, I have to recognize that technology changes things - sometimes in good ways, sometimes in not so good ways. I'm not really happy with my conclusion, but I've eschewed being a complete Luddite, because then, I'd just be a hypocrite. Waah!
