Uh, yeah, to actually answer this question - I have no idea. I stare at this stuff for days and play with it certain ways and think about asymptotes and higher-level polynomials and whatever you got. I got no answers. Throw me in a room with Khebab, a computer, a pencil, and a stack of graph paper and I'm sure we could come up with something. There's a couple other things you could throw in that room but I won't mention them here.
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.

 Our current government believes only in rationing by price. In other words, poor people can do without. And they count on apathy, we didn't protest the election frauds in two succesive national elections, we have allowed our votes to be manipulated by fraudulent refusals to count and by illegitematly disenfranchising huge numbers of people- oh shit, they're right! Mexicans have more cojones!
could adult beverages be one of them?
I was thinking more like basic office supplies. It's amazing what you can achieve with paper clips, magic markers, and a stapler.
