Yeah, those behemoths all share responsibility for killing the mom and pop stores. It’s not impossible to shop around to local variants. But probably the best solution is to learn how to kick the habit that American culture has foisted upon us all of buying endless piles of useless crap.
I cancelled my prime subscription years ago. I occassionally restart it for a month at a time if I need some esoteric hobby thing and I would be forced into paying for shipping or for prime. Then I’ll watch some stuff on their streaming service. Last time I used it, it was awful. Half of the shows were gatekept behind some ad system. And the “Amazon Originals” are all just extraordinarily expensive shows with terrible writing. Uhg. I am making it a point to not have an active prime subscription when Christmas rolls around. We (the collective we, as in, humanity) don’t need more garbage.
