Are you asking because someone using that name replied via gmail to your Wanted to Buy post and directed you to a Bitcoin ATM?
Funny you should mention that. I received the exact same thing down to the e-mail address. At first I was heisitant, but the individual kept sending e-mails confirming details (including the QR code) and more. Naturally I've asked for pictures of the item to confirm the authenticity of the sale, so I tend to think that it is legitimate. The seller in question also provided a real mailing address and did not bring up bitcoin payments until after I asked.
I'm open to ideas/responses.
