Ok just to give you an idea how this works. When te auction ends listia takes those credits that were bid and holds tem until the item is received by the winner. Then they release them to you. So you can't get scammed as a seller only as a buyer. I recommend that you ship with tracking so you are covered and can tell when the item arrives. But you won't get any credits until you ship the item an the winner receives it. That's to protect the buyer from getting screwed. So I hope you ship it out. I want to win.
Why do you really expect someone to say that they received an item immediately before you will even ship it. What's to stop you from keeping the item. You have no positive feedback. Listia protects your credits immediately. Sounds like you are the scammer. You apparently don't know how things work on here and you are not smart enough to scam people and get away with it.
