I posted a knife i wanted to trade got an offer for what I wanted. Yesterday I shipped my half . Sent the person i agreed to trade with a email with a tracking number . I haven't heard a word back from them since confirming they shipped . This person has a perfect feedback score and double the feedback i have. My question is if I don't hear back from them by tomorrow I was going to have my package stopped and sent back . It's out for delivery Thursday am I doing the right thing here, this has never happened to me before where i get no replies at all. If i let this package get delivered i will be out of luck .
