does anyone know for sure if a distributor will ship it in bulk?
I've already stated that U.S Goex distributors don't ship the loose bulk powder.
And my comments were with a certain assumption that people would also want the lowest cost shipping.
Goex Distributors also ship the least expensive, secure carriers, meaning UPS / FedEx / HSL, etc.
However, let me be much more clear in case somebody wants to start trying to split hairs:
The carriers that the Goex Distributors use, like UPS, FedEx, etc, won't ship cases of loose blackpowder in their delivery systems...only cases of BP in their protective cans.
You "CAN" have a plastic bag of loose BP in a cardboard box delivered to you by contracting a "common carrier" freight trucking line but the minimum shipping cost alone is in the neighborhood of $500 - $1000, then the price of the blackpowder...I didn't mention that as I assumed it would not be an attractive option to save money.
Hope this helps...but I think the best thing for you to do is just call a Goex Distributor then you can tell us...
