Why does gas fluctuate prices so much from day to day? Why don’t they have a set price, like how most goods are?

Answer 1

I’ve heard that the gas is just the reason for attracting customers, and the profit comes from the incidental purchases inside the store. The price you are paying doesn’t have anything to do with profit vs. what they paid for what they have, but rather what they expect to have to pay in the future to refill their underground tanks.
