It's called "gouging"...
...people want ammo and they know it.
But people remember things like that and when the current panic has passed you can be sure there will be many folks that remember who was an a$$hole and who wasn't...
...funny thing is that if it were some other commodity like gas, milk or water and people were buying it because thy were scared of some impending "doom", the government would step in and deal with any "gougers". But, since the people are buying ammo because of the current administation and said government is probably worried about and/or scared of a heavily armed populace, well, if anything they would likely be in favor of making ammo as expensive as possible.
Woah! almost crossing into tinfoil territory! LOL
