This number is a scam! It was a response from a Craigslist ad. When I responded, they said " due to the nature of my work I will not be able to come for inspection and am happy with the advertisement and wanted to pay through PayPal and have an agent pick it up"!
I just had the same person contact me about an item I was selling on craigslist. Used the same explanation as stated in "Grown" post.
It's amazing how bored people can get.
