Any rural community that has a trade deficit with the outside world slowly spirals into poverty. Buying local increases the number of times a dollar travels around the community before leaving.

There's a huge useful area between giving Amazon less power and giving them no power. Amazon is always the 4th place I look for something. Most of the time I never even have to go there. And things like their little tantrum where they stopped selling a bunch of Apple products just made that easier for me.

Also remember the audience. Most of the people who can't afford to shop anywhere but Amazon also can't afford to hang out on hacker news. Most of the people here can do better.
