Same as the previous comments. I suspected a scam and instead of just telling him to F... Off, I responded that I knew he was a scammer. Came from phone number 330-551-3417 which is also across the country from me.
As other users have said, 20 minutes after posting a Craigslist ad, I also received a text asking me to respond to this e-mail address if my item was still for sale. The phone number it came from was 330-269-9836 which is half way across the U.S. from where I live. Scam.
Also, got a text saying to email back to this address. I thought it was a scam. The number texted from was 205-549-2778. It just looked to much like what I put in and was asking if I still had it. 20 minutes after a post of course I still have it.
Posted a craigslist ad and 20 minutes later received a text message from this email address asking me to respond via email if I still had the item for sale. Looks like a scam as the phone number coming from the text is a San Martin, California land line number and well outside of my craigslist community. (669-257-3745)
