I did that already. 1159.65 for the boric acid and $412.75 for freight shipping on top of that. That's how I got my 1.06 per pound price. That freight is killing me
Welcome to TFP!
While this is the right chemical, it looks like it might be powdered and not granular though it's hard to tell from the photo. Powder will tend to sit on top of the water and also blow too easily in wind. This is why even from Duda Diesel we recommend getting the granular and not the powdered form of boric acid.
