Basically, if you need gasoline and the current price per gallon starts with $1.XX. go ahead and fill 'er up. The man will be raising the price 20-30 cents soon after.
Yeah, just don't understand it really. Oil keeps dropping, and I can't find any reason why gas would go up - no production problems or supply issues that I can see. I think the "Speedway effect" is probably the closest to being right. Biggest group decides it's time to re-gain some price in the market and most seem to go along with it. If/when others want to get market share they start lowering prices and the big guys then follow that too.
Still sucks how prices rise by relatively big #'s, but go down in a much more slow/orderly fashion.
Remember when gas stations used to compete with each other to see who could sell it for the LOWEST price? Now it seems to be just the opposite.
