^ To be honest i think you are jumping the gun a bit here.
Your auction ended the 23rd of last month.
Although she only has 4 feedback they are all positive and she has paid near $300 for an item, so there is no indication that she wont pay you,nor is there any proof in your post that she was lying.
Poor girl may well be telling the truth and have lost her father but in any case IMHO you are being very harsh without giving her time under the circumstances of her e-mail to you.
Whilst I appreciate she did not make contact untill you initiated a non paying bidder alert, please ask yourself if you would be thinking of ebay on the death of a beloved.
This is a big reason I am against this thread.
