small/medium shops have worked for me for the most part, only time I’ve had to use amazon in the last 10 years was for a replacement screen for a phone.

tho i dont live in america so have no idea if there is enough small stores to buy stuff from but i guess one should at least try buy from those whenever possible

That is what unions are for. In my country some years ago our postal workers’ union’s strike resulted in the prime minister resigning.

So unionizing and organizing a strike would be the most effective legal thing i would say.
