So everyday is OK to sell overpriced items but during a crisis everything should be on sale?

I get things become a necessity but let's face it most people do not prepare prior to a hurricane or a rainy day... Period. It is their own responsibility to prepare for the worst. If someone takes advantage of a sale and ends up making money from it during a time of crisis then the market has spoken. Sure people can give things out for free but things aren't free.
