Not Sure If This Is OK Here, But Here Goes

PayPal is secure. I have used it for the past five years without any problems.

Of course paypal is terrific and an accepted industry standard. People do try to game it by for example claiming all sorts of nonsense, I know that, but I am only going by what others have said.

Complicated transaction, though, and of course it smells fishy. My preference - for want of a stronger word, maybe "rule"- is to always and only communicate with the buyer to whom you will ship it to. Or, seller, whatever side you are on.

This approach is also consistent with any ordinary rules of contract law.

Keep it simple. Hows that for some original advice.

I believe PayPal has something in place that you have to ship to the/an address on their PayPal account or it's not covered. I may be totally wrong but I won't ship anywhere except the PayPal address.

I'd wait a while and see if I got any other offers, and I'd also list it on USAudiomart.
