Sorry if it appeared I was trying to flame the OP. I googled all I can find is this post. Also it looks like a drive-by posting. Op has not responded to any of the after post so we have no clue as to how it was advertised to be.
He stated that the person he dealt with on the phone said he would credit the 15 pieces towards any future orders. That sounds fair to me. If I had sold it I would have done the same thing.
Would you want to spend $2.50 to ship 50 cents worth of brass?
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
