    Was Suckered by the Word "Pure"

    Was advertised as "pure" potassium nitrate. Instead, according to their own label, it's only 38% potassium nitrate. 46% of what I paid for was potash. Not much good for hot-bluing steel. I have to assume they meant the 38% was pure. Furthermore, I paid for FedEx and it was shipped via USPS instead. Lesson learned. They will not get another penny out of my pocket.

    Prompt delivery and correct item.

    Item is exactly what I ordered and came in a timely manner. Only confusion I had was brand. Original add said I believe Seedbarn brand but I recieved a Haifa brand. Again its exactly what I need so it doesnt matter.

    Works Great

    I bought 2 lbs of this for $5. This is the cheapest that I have ever found it. I just mixed it with some sugar and tested it. Works great!
