I have previously purchased boric acid from Duda Deisel as well as a few other eBay sellers for around $2 per pound delivered.
I just discovered that eBay seller, prosupplyoutlet, has 25 lbs for $30.33 with local pickup in Rancho Cordova ($46.88 delivered).
Super nice and professional outfit, easy Borates!
For comparison, Sierra Chemicals in West Sacramento wanted $2.24/lb with local pick up. Nope.
