It IS free enterprise. If you feel that it's taking advantage, so be it. If you were to sell your primers for a good price, say $80 per K, is that gouging?
So you sell them for $80 per K and the purchaser now goes out and sells them for $160 per K, is that gouging?
There are many circumstances that can dictate the price, among them might be how hard up a person is that is doing the selling. If the "gouger" hasn't worked for months due to the Pandemic and needs rent money or food for his kids, you don't think that guys going to get all that he can to feed his family?
There are many other instances that lend themselves to the stated "gouging", many that have similar stories, a true need.
Not everyone is "gouging". But even at that, it IS free enterprise!
