I just received an email today from Powder Valley, stating that they have reduced their Hazmat fee down to $19.95 through 12/31/2017.
That's not a big reduction, but $8 cheaper isn't anything to just ignore either. And they generally have decent to good pricing on the items they carry too, plus their shipping charges aren't outrageous either.
Just figured I would post it here to catch your eye if you are thinking of placing powder or primer orders between now and the end of the year.
