Clark's Donuts in Butler.

Customers left Clark’s Donuts with smiling faces Thursday morning, Aug. 21, including one couple carrying 10 boxes as they got in their car.

“We needed something new like this,” said Barb Blakley outside the shop. “They have a nice selection and are very fast.”

The newest shop at 126 Point Plaza opened at 6:30 a.m. Thursday and sold out by 1 p.m.

It sold out by 10:30 a.m. the day before, according to the Clark’s Donuts Facebook page.

The business has locations in Butler, Franklin and Seneca in Butler County and one in Grove City, Mercer County. The donuts can also be found in convenience stores and markets throughout Western Pennsylvania.
