A man selling an iPhone X didn't look hard enough at the money in an envelope given to him by the buyer.
The money was fake and the seller was out $860, Madison police said.
The scam happened at about 12:20 p.m. Wednesday in the parking lot of a Kwik Trip store, 1625 N. Stoughton Road.
The 24-year-old man selling the phone advertised it was for sale on the Letgo app. The buyer contacted the seller and a meeting place was set up at the Kwik Trip lot.
"The buyer arrived and handed the victim a cash-filled envelope," said police spokesman Joel DeSpain. "It wasn't until after the deal was done and the suspect had left that the seller took a hard look at the bills."
There were 43 $20 bills in the envelope, all fake. 23 of the bills had the serial number MG25812709F, and 20 had the number MG25812710F.
Little suspect information was given by the victim, only saying the scammer was black, 6 feet tall, slender build, wearing a knit hat.
