Buy things used, not new. Just buy it on craigslist. The upside is that you don’t have to deal with all the packaging material.
Resist buying stuff on Amazon, as it is a pain in the ass to get rid of all those cardboard boxes or plastic covers.
For coffee, just drink espresso at the local coffee shop. Just drink it in a “for here†cup, drink your shot, and then get on with your day. Don’t deal with the stupid plastic or paper cups.
