I made an agreement to take a guys rifle at asking price, he said we’d meet after lunch. Now he’s not answering texts or phone calls, he said he had a trade offer he wants to look at (that came in after I told him I’d take it and he agreed on a meeting time) he has a zero feedback, I have all positive. Our interaction was all through text message. He’s a 25 year old kid and has no idea what man rules are. What to do?
