For sellers who want to sell at the same mark up as pre panic this is the only way they can keep any product in for more than seconds. It does serve to get people in the store, often a LOT. Many seem to enjoy driving to store after store to check the shelves. Hey why not. I suspect some of the people doing this must now and then spot something else they want and buy.Well, they limit purchases to 1 can of powder and 2 boxes of ammo per household, per day.
This does set a lot of people off. Of course those who don't like this should know that if the store did not set a limit the first person in line would just buy all the stuff, then they would be mad at that.
If the store set the price so high many would not buy they could keep the stuff a little longer and this would set off a lot of "I will never shop there again".
So again this panic has not been a year long yet but many who seem to have no memory at all act like it's never happened before and has been going on years
The last great one lasted couple years IIRC, came to an end, everything was available and on sale weekly. No one wanted it. This one too will end, those screaming mad will ignore the stuff on sale until it happens again
