It's normal to see people posting pictures of their Halloween costumes this time of year, but don't be surprised if you start seeing pictures of gas signs.
The national average price of gas dropped 33 cents in October, landing at $3.00 on Friday, according to AA. It will soon dip under $3 for the first time in four years.
"It's stunning what's happening here," says Tom Kloza, chief oil analyst at the Oil Price Information Service, according to the Associated Press. "I'm a little bit shocked."
When the national average crossed above $3 a gallon in December of 2010, most drivers weren't sure they'd ever see $2.99 again.
Since people in developing countries bought cars by the tens of millions, demand for oil and gasoline was rising and turmoil was brewing in the oil-rich Middle East. Now demand isn't rising as fast as expected.
Drillers have learned to tap vast new sources of oil, especially in the U.S., and "crude continues to flow out of the Middle East," according to the AP.
Though season swings and other factors will probably send gas back over $3 sooner than most people would prefer, the U.S. is on track for its lowest annual average since 2010.
Better yet, the 2015 national average is expected to be even lower.
Trisha Pena of Hermitage, Tennessee, paid $2.57 a gallon to fill up her Honda CRV recently, according to the AP. Like most people around the country, she was so surprised and happy by the price she took a photo and posted it on social media.
"I can't remember the last time it cost under $30 to put 10 or 11 gallons in my tank," she said in an interview. "A month ago it was in the $3.50 range and that's where it had been for a very long time."
New York's average of $3.37 is the highest in the continental U.S. South Carolina and Tennessee meanwhile are the lowest, with an average of $2.75, according to the Associated Press.
Happy Halloween everyone, enjoy your treat while you can.
