Hiro and Shannon Kimoto spent more than $600 on gasoline for their business in May.The married owners of Handy Hero, a handyman and home improvement business in Cumming, said they’re glad to see gas prices coming down a bit, particularly at a time of year when they normally rise.“When it goes down, it definitely helps,” Hiro Kimoto said. “When it’s 50 cents less, then I can do a lot more mileage with that, so that helps.”For Justin Fulkerson, manager of B.L. Mullinax Landscaping & Shrubbery in south Forsyth, lower gas prices can equate to reduced expenses and more business. “The main thing with us is sending out deliveries,” he said.
