I prowl the bargain shelves of all varieties of supermarkets for sale coffee: Sprouts, Grocery Outlet, Safeway, Walgreens, Target, etc.
Whole bean is preferred, but ground will also work.
My expectations are low, and I never feel like I’m getting ripped off.












A bit late, but I’m glad you found a solution!
The only thing I would add is the heat on/off technique, here by James Hoffmann but he credits The Wired Gourmet for coming up with it.
For me, it helped get rid of this nasty burnt taste in my moka brews.
I hope this helps.
