My recollection of how the scam worked was that they messaged me after the sale to say the iPad was a gift and could they send it to some other address than the PayPal confirmed address, and also not include any receipt info in the package that could spoil it as a gift.
It looked like the classic drop shipping eBay scam where I’d find out from PayPal that a stolen card was used, the charges would be reversed, and I’d be out the iPad and the money.
