UNA, Miss. (WTVA) -- Knox Grocery owner Barry Smitherman said butane is in high demand right now.
His customers don't want to be caught without it for the colder temperatures coming.
They all were concerned about running out for Sunday because we don't have Sunday sales," Smitherman said.
He said the last few days have been busy and he expects Saturday to be the same.
"I've sold several bottles this morning and I plan on it being busy today," Smitherman said.
He added that his store sold 500 gallons Friday night alone.
Those who heat their homes with butane said it is essential during the winter.
Customer Eddie Binder said he's been heating his house with it for 15 years.
"Burning electricity is so high, but the butane is great," Binder said.
Binder said a 25 gallon tank usually lasts him a long time.
"For me, it probably will last three weeks," Binder said. "Depending on the weather."
Which Smitherman said is typical for his customers, but with colder temperatures on the way, he said he's noticed them filling up more frequently.
His staff will be standing by to fill these needs.
"I'm going to make sure I have people here to pump it all day up until 8:30 tonight," Smitherman said.
He said people from all over the area go to his store because working with larger distributers isn't as convenient.
"We sell small amounts," Smitherman said. "We fill the small cylinders, where as the gas company they're not going to come to your house to fill a small bottle."
Which he said he's happy to do because he has so many loyal customers.
