Now people across the country are talking about the woman who decided to pay it forward.
Katie Kanefke needed diapers for her son Marcus and asked if the store would price match four boxes, but it could only match one.
That's when Carol Flynn stepped in and another shopper shot what happened next with his cell phone.
"It looks to me like you had four boxes of pampers and you're only buying one," said Carol. "So I said 'Do you have children?' 'Yes, I have a little boy who is four months and he uses a lot of diapers.' And I said, 'I think you need the other three boxes then.'"
Carol decided to pay it forward and bought the extra diapers for Katie's son.
"I said, 'Someday you'll do this. Paying it forward is kind of a neat thing to do, and I'm sure sometime you'll pay it forward to somebody else.'"
