This is a great time to get to know your LOCAL reloading supply shop. What I have often suggested to my reloading students is that after making a lot of effort to get to know the owners personally, you should then offer to pay up front for supplies. This does work. They feel obligated, since they are sitting on your money, to put you at the front of the line. They will thank you for trusting in them. And, that makes for an even more solid relationship. I have a standing positive cash account at two of the local (to me) suppliers. I just don't need anything at the moment (planned way ahead of all of this and am sitting proud on primers and powder.) Overall, it's a short amount of cash to have a great relationship with these local guys who are under pressure from the general public. When I walk through their front door, I'm never just "another customer".
Try this, and report back.
