Not only an US issue. In Germany the gas price is jumping up and down twice a day, the amplitude is up to 8% from the all round price. So you can get a litre of 98 octane for 1,60 € in the morning. If you miss that opportunity though, you sometimes pay 1,72 € in the afternoon. Next day maybe 1,65 € again and so on....
