A West Manchester Township mother of three will be featured on ABC's "Nightline" for her experience in frugal shopping.

Armed with a well-planned grocery list, local blogger Sarah Mock will teach viewers how to save money during their weekly food runs.

The segment will air at 12:35 a.m. Tuesday and follows Mock through Aldi's, Amelia's Grocery Outlet and Giant stores.

"I've been a frugal person my whole life," said Mock, who operates howipinchapenny.com.

She started her blog about 5 years ago when her husband went on unemployment and they were expecting their third child, she said.

"We had to tighten even more, and I knew there were other people out there going through the same thing," Mock said.

"The blog is a reflection of our life at home and shows people how we save money for our family," she added.
