WATCH: Mother ‘sees God’ while buying diapers at Wal-Mart

SIOUX FALLS, S.D. — “If you ever needed a sign that God’s there for you in the hardships and the struggles, this is it,” Katie Kanefke said after a recent shopping trip to Wal-Mart.

The South Dakota mom was at the store buying diapers for her infant son when she asked Wal-Mart workers if they could price match all four boxes of diapers she planned to buy. Workers said no, that they could only price match one of the boxes.

Unable to spend too much money, Kanefke was going to put three diaper boxes back on the shelves. That is when fellow shopper, and total stranger, Carol Flynn chimed in.

“It looks to me like you had four boxes of Pampers and you’re only buying one,” Flynn recalled saying to Kanefke.

“So I said ‘do you have children?’ And she said ‘Yes, I have a little boy who is 4 months and he uses a lot of diapers’ and I said ‘I think you need the other three boxes then.’”

Flynn “paid it forward” and bought the extra diapers for Kanefke’s son.

“I couldn’t believe it. I was just so surprised. I was like I don’t even know you,” Flynn said.

A third Wal-Mart shopper recorded the act of kindness on video.

“I never expected to have it videotaped,” Flynn said. “It went viral, which I’m told meant you could go on Facebook and find the article, which I did.  It was very surprising to me.”

Flynn told Kanefke paying to forward was a “neat thing to do” and encouraged her to pay it forward to somebody else.
