Pay Pal Protection?

You need to direct all questions to paypal.

You should be covered by their policies. Audiogon is not the one who will issue the refund. Read their policies as well.

Read the information that Paypal posts on their site. Also note there is a resolution process both parties go through. See the menu on the right side of the page as you scroll down.

You should be covered but if paypal can't or won't help and you processed the payment with a credit card, the card companies can be really helpful.

Also, if you ever need to return an item that you used paypal to pay for, ALWAYS use a credit card as the funding source and NEVER send the item back before you file a claim with Paypal. It may seem adversarial but unfortunately it's the only way they will stand behind you if the person on the other end tries something funny. I just went through this with a pair if ICs and luckily I used my cc as the funding source so the cc company took over the claim when paypal told me I was out of luck.

Good luck.
