Not interested in hoarding.
Somewhere in between "I'm not buying primers until they come down to the price I last paid for them back in 1950." and "Armageddon is coming! Buy all you can at $5/primer if you have to!" has to be a reasonable line.
Until prices really drop my general rule is when I crack open the last box of a thousand, search for another thousand. I do the same with groceries, when I open the last bottle of cooking oil buy another.
With that being said is 9.5 cents/primer about the going rate for Winchester 209?
