At First Fuel Bank in St. Cloud, Minnesota, anyone off the street can buy gas futures at the pump with no service or storage charge, just a $1 lifetime membership fee:

A year ago, the retired milk truck driver bought 500 gallons of gas at First Fuel Banks, locking it in at the then-current price of $2.03 a gallon. He taps that reserve whenever gas rises above that mark. If the retail price drops below $2.03, he can leave his reserve alone and buy elsewhere.

Altrichter said one of his neighbors got in at First Fuel Banks several years ago and is now is withdrawing from a reserve that cost him 99 cents a gallon. "How about that!" he said.

Each station has a 50,000 - gallon tank for each grade of gasoline - regular, mid-grade and premium — compared with 6,000 to 8,000 gallons for each product at a typical convenience store, Feneis said.

That's enough capacity to handle short-and medium-term demand, he said. For people holding onto reserves for a year or longer, the company hedges its obligations by buying gasoline futures contracts on the New York Mercantile Exchange.
