I miss Radio Shack, particularly when they were a bit more "component based". As a general electronics store, they were almost always strictly worse than any of the big box stores, but if you needed something like a resistor or individual LEDs, it was great to be able to be able to drive over there and find something. I live in NYC now, and fortunately we still have Micro Center which is still fun, though I do worry that it might go the way of Fry's Electronics soon enough.
I understand it, it's really hard to compete with Amazon in today's environment, and I'm not judging anyone for using Amazon instead of buying from a store, I buy online too, and fundamentally these are for-profit businesses and I don't feel any obligation to give them charity.
Still, seeing Radio Shack and Fry's dying does make me a little sad. When I first moved to Dallas, one of my favorite things to do on the weekend was go to Fry's, look around the store, and buy a cheap DVD of some anime that I hadn't heard of.
