That is a fantastic deal for meat you can feel good about! I pay that much for pork at the big organic grocery chain in Germany (ebl) that I can only hope they’re telling the truth about, and far more for the occasional beef steak there.
This isn't a special deal either, this is how the guy makes his living, along with some other farm products.
Grass-finished is really tough economically; corn results in an animal almost 3x the size.
The only grass-finished place I have is struggling no matter how much beef I eat :) I really need other places if it goes away.
