And far too big of a price fluctuation to be justified. Case in point is when the prices recently rocketed from 3.79 straight to 4.19. Now they've feathered down to 3.59 or so. You can't tell me that supply OR demand have changed that much. No, there was flooding at the time, and even though it didn't cause any real problems with supply, it was an excuse for big oil to stick it to us.
