I've purchased bones from the dairy and beef guy at TSH. He's only the on certain days and you have to ask him. You can also get organ meat from him.
No you can not purchase bones from Three Stone Hearth.
I haven't seen bones either, Berkeley bowl has a good selection if you've got a bone to pick
I've never seen bones at three stone hearth. They sell homemade broth tho. If you want to make it at home I would recommend The Local Butcher (for pasture raised, organic) or Magnani Meat Market to purchase all kind of bones
