<prompt> Human: Hello all! I put a listing to sell a collection of cards on craigslist and within hours someone accepted the offer. A few things seem suspicious about the whole thing. He told me to email his wifes email to talk about it. He also is pushing to buy it ASAP. What worries me the most is he said he is sending a courier to pick it up then he will pay me through paypal. I know not to give the cards over until I have the money in my account, but is there another way this could end badly for me?  <response>: courierIts a scam. People that want things on their doorstep click Buy it now on eBay, pay through PayPal, and then wait 2-4 days for their purchase to show up in the mailbox.Craigslist is local, with cash.
