Doesn't matter what the price is if there isn't enough for sale

Unless there's a single buyer, or at least a coordinated decision of "above this price, we all buy nothing, and below this price we all buy our normal amounts", it truly does matter what the price is when there's not enough for sale.

The price is determined by who needs it the most and is willing to give up the most cash. Instead of rationing by lines, or fixed quantities, it's allocation to those who can either make the most out of the jet fuel, or those for whom money is the least valuable.

That's not how supply and demand works.
