(Radio Iowa) – The C-E-O of the Casey’s Convenience store chain says customers are continuing to weather the economy with a few changes in spending. C-E-O Darin Rebelez says 75 percent of their customers are upper income, or make 50-thousand dollars or more a year. “We’re in a very affordable geography so that 50-thousand dollars goes a lot further in our footprint than it might in some other geographies,” he says. “So all that being said, in the upper end, we’re not seeing much change with the consumer. They’re visiting the store as frequently buying as they have historically bought.” Rebelez says those on the lower end of the economics have made some changes.
