buyer cheated me first and why shall i stay to be "束手待斃" I can swear to god that i mailed it on time and to her paypal address.
she bought another similar item (not the same but very similar) from another of my ID and she received that one OK by leaving me + feedback. I would assume she received the "lost one" as well.
As long as tracking info shows item delivered, she would lose the case. That is for sure.
