You can spend $30 on equipment and another $8 for a pound of beans

OR

You can spend $300 on a burr grinder $150 on one of those neat vacuum brewing devices, and who knows how much for fair trade single source coffee beans roasted in your back yard

Or you can find a balance that gets you things you care about (fair trade beans, good roast, a nice grinder for flavor, whatever your taste might be) at a lower price than going all out

When it comes to underwear or other clothing items, I'm generally willing to pay a bit more if I know that I'm avoiding plastics and pollution and the workers who make the items aren't working in sweatshop conditions
