A Sheetz on Hopson Road just got in a delivery of propane tanks on Thursday afternoon after waiting for days.
A cashier at another convenience store up the road on Highway 54 said he sold out of propane tanks before the last storm, and the supply has not been replenished.
Durham Fire Deputy Chief Christopher Iannuzzi is urging people not to use an outside grill indoors, either for heat or cooking.

Iannuzzi said people have done that in the past, and it is extremely dangerous.
He also says only kerosene should be used for kerosene heaters.
"If you use gasoline in a kerosene heater, when you go to ignite it, you're going to get burned because it's going to explode," said Iannuzzi. "It's going to flash, and it's also going to catch your house on fire."

Chain cables were wrapped around fire truck tires. The tool was used in last weekend's storm.
