Coffee grinders are ten bucks and beans last longer if they're not ground.
Also, everyone has the things that they choose to splurge on, even a poor person. When I was dirt broke in college I still bought 2 ply tp because dammit life is too short to deal with anything less. I don't regret it.
Huh? Whole bean coffee doesn't cost any more and some grinders are quite cheap? The vast majority of poor people have smartphones, and those are much more expensive.
