I guess I'm just wondering if the psychology and market forces are the same between the price a refinery is willing to pay at any given time and what a consumer is willing to pay.  A consumer is more likely to panic and pay any price. While a refinery will have long term contracts and savvy purchasing agents willing to negotiate down to the last cent.   I would also thing that at a certain price the government will step in with rationing.  This would create a black market with even higher prices.  

It's and interesting concept to ponder.  Eventually reality will step in and give us an answer.
