Marshall,
   
  Here is the URL that V sent which is posted below your post:
   
  http://store.yahoo.com/herbal-remedies-usa/diead6oz.html 
  
  That site charges $6.95 for 6 oz of DE Food Grade + S&H which is somewhere 
around $1.50/oz.
   
  THAT is where I got the price.

    Why do you think there would be anything wrong with it?  They would be 
selling food grade, not the swimming pool stuff. 
    I don't mind giving some away for flea powder to my neighbors that way and 
it certainly hasn't hurt my dogs and cats.  THis is the first that I've even 
heard of food grade DE. One of the reference sites says that if you have eaten 
anything made with wheat flour you have eaten DE.  Apparently because it is 
used an an insecticide in the grain storage facilities.  At $1.50/oz I 
seriously doubt that they are using food grade for a silo of grain.   Where did 
you get that absurd price?  Food grade DE sells for about $2.50 a pound, not 
$1.50 and ounce. 
http://www.gardenharvestsupply.com/de_permaguard.aspx so adding about .1% of 
that to a pound of flour would only cost about .2 cents.   Marshall 
  
  I'm going to have to read a lot more to find out just when/where/why the DE 
is heated and how much.
