Person tries to 'buy' items on Craiglist remotely, sight unseen, and pay with Paypal. That is the hallmark of a scam, the money will be refunded later.
This caller tried the same scam with me. Wanted my paypal account. Told him cash only and that his number was coming up as a scammer and didn't hear from him again.
Replied to my craigslist ad almost instantly when I posted it. Was "OK with price, let me have your paypal email account so I can proceed with the payment and my shipping agent can come for the pick up in your house".... The item was a couch! SCAM!
