General Manager Shawn Hart said just this week alone he has sold eight batteries. “I’ve noticed in battery sales this week and it's only Wednesday, and we’ve sold eight batteries. We’ve seen an uptick in phone calls my car won’t start or my car broke down and the other thing is tires. Tire warning lights are coming on so a huge uptick in recent weeks,” Hart said.
