a brick of primers for $75. Is that 1000??
Yes. A "brick" is a thousand - 10 "packages."
(A "package" contains 100 primers.)
A "case" is five bricks (5000).
Dont pay the gougers/scalpers.
"Gouging" exists only in the mind of the buyer. If you aren't willing to pay the price, then it's gouging. If you are, it's not.
