I agree with you that there are many different pros and cons to price gouging. It is true that in theory raising the price of necessities such as food, water, and gasoline during a natural disaster could lead to people buying fewer items.

I agree with you that the prices does need to increase on these items to help pay for the rushed shipping, so people can receive the supplies
