I would recommend alerting the buyer that you will contacting her local police department and the postmaster general and asking them to investigate her for fraud, and that you intend to press criminal charges to the letter of the law. Would also mention that you may also file a civil suit against her as well for any funds she takes back from you + court fees + expenses for your time spent in this endeavour. Would also suggest you disconnect your bank account from your paypal account now (they can not authorize a charge back on your credit card without your consent). I think the criminal investigation for fraud may get the buyer's attention. Don't waste your time with ebay and paypal stating your case - I speak from experience here. I had a buyer buy a jersey from me via paypal with a stolen credit card. The buyer ended up with the jersey; I got nothing except the finger from paypal as they quickly removed the money from my account. I asked ebay to, at minimum, suspend the person's ebay account - they said they'd look into it, but never did.
