SAN DIEGO (KGTV) -- A local woman who was trying to sell a GoPro camera has a warning for other online sellers: take a close look at what you're getting back.
Jessica put her camera up nine months ago on the app OfferUp, after getting a new one for Christmas.
It didn't sell until she got a message on the app Thursday morning from someone named Jason, who typed,"I'll take it Jessica where can we meet."
After a brief conversation, Jessica asked to meet at a 7-11 near her home in Normal Heights. When she got there, a casually dressed, polite man in his early 20s inspected her GoPro, before agreeing to buy it for $200.
"The man took two $100 bills, folded them in half and them handed them to me," said Jessica. "Nothing seemed suspicious to me, so I just kind of stuck it in my pocket."
Soon after, she was back home.
"As soon as I felt the dollars I knew. They had a waxy feeling ... held it up to the light to find the strip and there were none, and I knew they were fakes.
She handed the bills to a Secret Service agent, who said they were poor-quality counterfeits. Jessica says she was kicking herself for not catching on sooner. Still, Jessica believes the man is no amateur.
Looking back, she believes the conman had done it before and will do it again.
"He knew what he was doing. He parked in a spot the cameras couldn't see," she said. "His car was blocked by a truck. He was very calm."
