Down by Pennies, Up by Nickels and Dimes

The gas price went back up yesterday--14 cents! It's amazing to me that it goes down by one or two cents, but when it goes up, it's all at once. I do not begrudge Exxon-Mobile their record profits last year. The economic illiterates that report the news ignore their profit margin (barely 10%) because that's not nearly as good a story as "record profits" for oil company. But I do hate the way the gasoline prices are manipulated at the pump. If it can go up that fast, it could come down that way too!
