Alf,
I am starting to see the same as you. Like others, I am buying powder and primers every pay cycle. I learned a lesson from the last round of this. Buy when you don't need them because when you need them, buying them might be out of the question.
For right now, I have a local shop that is able to get primers (Federal too) and I am focusing on them; plus the price is around $30/1000.
