A Colorado Springs man has a warning for everyone to be careful if you post an ad on Craigslist.
He tells 11 News a scam artist contacted him, and tried to steal his money.
David Bannister said there were red flags right away, as soon as he was contacted by the scammer.
Bannister posted an ad on Craigslist for an RV generator, asking $1,200 for it.
Within hours, he got a message from an interested buyer.
The buyer sent him a check for more than $2,000 over the asking price. The buyer wanted Bannister to cash the check and send the extra money back to cover the cost of shipping.
That's a red flag, and Bannister had his suspicions right away.
"People just be aware. If they're gonna send you more money, they're not sending you anything. They're just trying to rip you off," said Bannister.
David tells 11 News he took the check straight to his bank, and they confirmed it's a fake.
He hopes by sharing his story, he can help keep someone else from falling for the scam.
