"If they don't want to meet you [in a public place], that should be a red flag indicating that you do not want to conduct business with that person," Roswell police posted recently on the department's Facebook page.
Many metro city and county agencies -- including Holly Springs, Kennesaw, Marietta, Smyrna and Snellville; and Cobb -- provide safe spots to meet.
For example, Smyrna police provide "Operation Safe Sale" 24/7, and can provide an officer to witness any transactions, as well as check to see if the items in question (even cars) were stolen or lost.
"These transactions are risky," Smyrna police told WABE. "Just adding this one more step is just kind of like a no-brainer to us."
On Friday, Marietta police announced a similar program, called "Meet, Screen, Exchange," which provides a "safe haven" at the department.
"Personal safety is more important than getting a great deal, especially when the deal may turn out to be a ruse to isolate someone in order to rob them," they said in a statement.
No appointment is necessary, as the department is always open, and the service is free of charge.
