Around here, gas prices have both risen and fallen on practically a daily schedule. On my way to work, the price may be "low", then on my way home, it's risen up to 20 cents higher per gallon. I'm not exactly sure why there is all this fluctuation every day, but I am sure that it's high even when the price seems to drop a few cents. Adjusting my budget to include gas is growing ever more difficult, but there is no public transportation in our rural community, so it has to be done.
I do shop around for gas for the lowest price I can get while still avoiding a certain gas company that has Communist ties. I won't mention the name here. It's easy enough to research this online. But shopping around for gas doesn't mean I drive all over the place. It only means that I keep a sharp eye out while driving and I don't let my gas tank go so low that I am forced to get gas at the first place I come to.
Of course, I do this sort of comparison shopping everywhere I go. I check prices to make sure I'm getting the best deal. It's the only way I know of to keep a reasonable budget intact. Even with online sources, it's a good idea to check around on the internet whether you're shopping for shoes or diet pills, to be sure you are finding what you need at a reasonable price.
