I stumbled across a guy on Craigslist that has thousands of used, but excellent condition fire brick for sale for $0.25 each. I picked up enough to do my 42" oven and an outdoor fireplace.
Also, if you are looking for Perlite or Vermiculite, don't go to any of the local retailers as they run about $30 for a 3.5cf bag. Go straight to the manufacturer down in Chandler. You can get it for under $8/bag, and if you bring a trailer, you can get a HUGE bag of dust for free (if you happen to be mixing it into soil for a garden or something).
