Buyer anxiety

I have purchased  an integrated amp here on Audiogon. It is my first buy here. I tried to pay with Paypal but the transaction will not complete. I sent a message to the seller asking for advice. She is asking me to pay her directly to her email at Paypal. I'm not sure Paypal will back up a purchase with a private individual. 

This is her message to me.

Hello Dear, I Hope you are doing well.

Sorry for my late reply, I tried to contact you through audiogon, 

For the confirmation process and for your item to be shipped to the right address could you please give your shipping address and send us a screenshot of your payment from PayPal.

Your order has been prepared and ready to be shipped tomorrow, please confirm the previously requested details.

The red flags are 

They have no sales history.

There is no discussion history under Witting74

The amp is supposed to be in Kansas, but the phone number is out of country.
