Please DO THIS, DO THIS, DO THIS!!! WHAT GOES AROUND COME AROUND, B****!!! Sorry to be shouting here, but I absolutely hate it when a fellow pfer is taken advantage of!!!you should have someone do a buy it now for you and then do a chargeback on her. You will have your purse back and the cash! Sounds wrong i know, but paypal nor ebay does crap to help us out - as you found out. The way I look at it, you are just getting your bag back.
And YES , it's just right you wrote her that email!!!
