Sorry to hear this happened.

This is one reason I don't make purchases w/strangers on CL. Better IMO to go through eBay, and choose someone with 97% + high ratings from thousands or hundreds of confirmed eBay buyers. Another option is to purchase online from established, popular and reputable companies only. That'd be my advice for your friend going forward. Too bad she had to learn the hard way.
