I just tripped over this ad:
https://kalispell.craigslist.org/mat/d/bigfork-insulating-fire-brick/6941073454.html
TLDR is he has lots of new fire brick available for $1/brick or a pallet of 684 for $200.
That's perhaps 90 minutes from me, but
I think it's a very good price. Is it?
How much do you pay for fire brick?
If there's others in the area that want to go in together on a pallet I'd be open to it.
(Should I have posted this in the Missoula forum instead? Moderators please feel free to move it if appropriate.)
