It happens both ways though.. the price can go down regardless of when a truck comes in. They adjust the selling price based on the price they expect to have to pay to replace it (sorta.. complex formula ).

The prices going up with the pump had a lot of do with the media and people having a the skys falling attitude.. if everyone across the country didn't rush to go get gas immediately prior to Ike would the price have gone up as much? I think it was more of a perceived shortage than anything based on fact. With the refineries tempoarily shut down yeah some areas may have ended up with shortages.. but not everywhere.
