I have a heck of a time finding local sources for some of the powders you guy's often recommend (i.e. APP, Black Mag etc.).
However, even if I was willing to pay the shipping charge for a small quantity of of these powders from various on-line sources, the Haz. Mat. fee croaks me.
Any suggestions?
Also, is the Haz. Mat. fee the same regardless of the quantity you buy?
