On one hand, FBO managers need to base their posted retail price on the wholesale figure they paid for the fuel when it was delivered; but they also need to consider their cost to replace that fuel. If they bought low and prices skyrocket, they could be in for windfall profits; until they have to call the supplier to reload. Conversely (as is the case these days), when an FBO buys a truckload of fuel at prices based on $140-per-barrel oil, it takes a gutsy move to lower retail prices to well under wholesale level on the fuel that remains in the tanks. What if wholesale prices soar again in the weeks it takes to empty the fuel farm? Then it becomes a CFO's nightmare of buying high, selling low, then being forced to buy high again. So if we want FBOs to lower prices, maybe we should just buy more fuel, more often, so their selling price can better reflect their day-to-day wholesale investment.
