Yes it was a scam. Oddly enough my friend was emailing the guy and he needed the money to send to his pregnant wife in Maryland who also had breast cancer and wanted it to be sent via Walmart. The address for the FFL that he gave showed up as an empty building where the phone did not work. Also...
There was a guy that listed a Wilson CQB for $1000 then it disappeared. I was making sure I wasn't just seeing things. Made me a little suspicious though.
