King is the President and CEO of the Western Pennsylvania BBB.

He says the organization “crowd-sources” scams through its Scam Tracker program. That’s how investigators found a mom in Munhall who became a victim on Craigslist. She bought tickets to the Ariana Grande concert at PPG Paints Arena for herself and two teen-aged daughters.

“In this particular case, these tickets would normally go for $300. And on Craigslist they were $175. That’s the first red flag,” explained King. “She goes and pays the scammer, and three hours later, she gets a notice from Ticketmaster saying these tickets were bought using a stolen credit card and they were illegitimate, and there was no way she was getting a refund.”

The Better Business Bureau urges consumers to purchase tickets to events from a trusted and licensed source and to use credit cards when possible.
