As per Bruno's: "There is a minimum order of 3,000 primers and/or 3 pounds of powder. The reason for this is because of the relative cost between the item cost and the shipping and haz-mat fees. $50.00 estimated haz-mat and shipping fees. Ordering 3,000 helps to offset this cost."
WTH! They don't cover the shipping/hazmat, the buyer does, so what do they care if a customer only wants one box at their already ridiculous retail prices?! No wonder they have them in stock.
