My wife and I split a pot a day, brewed on a Moccamaster. We buy bulk from a local grocery store a lb at a time and go thru about 3 lbs a month. At $12/lb, we’re at around $40 a month.
During the winter months I go to a coffee shop down by the Seattle waterfront. I do it because they’re starving in the winter and I want them to stay open. Couple times a week, $5 with tip for a drip.
