Bulk powder comes in a 25# box lined with a plastic bag. I transfered it to my empty 1# cans (you have been saving your old bp containers, right?) using an ice scoop and funnel. Did the transfer outside in case of spark.
I just heard back from them. They sell for $19 per lb or $350 per 25lb case (I'm getting confirmation if that is 25 cans or bulk powder). They do charge a $32 hazmat fee on top of shipping if you want it shipped.
So, per case, that is probably the cheapest I've been able to find it by about $100, especially if you can avoid the hazmat/shipping fees. That might be worth an hour drive each way.
I buy my 1F powder from powderinc. They will sell you 25#'s for $360 INCLUDING shipping AND hazmat fees. This is NOT bulk - it comes in 1# cans.
I take it you are using KIK powder then? How do you like? Have you compared it to Goex or Swiss and if so, how does it stack up?
