When I ordered from Admiral, I specifically asked them if there would be any "hidden" fees. "No" was the answer.
My invoice included a $25 packaging fee (plus shipping) that was not discussed. That brought my 25-lb piece of 1075 from $4 per pound to $5 per pound.
Now I just buy 1075 from McMaster Carr. Price is straightforward, and I have it in 48 hours. McMaster-Carr's 1075 is cold-rolled, while the stuff I got from Admiral was hot-rolled.
