Update.
I was able to find the third party's phone number from their website (enkarga.com 305-677-0187), and they confirmed the transaction was done by this buyer (whom, Enkarga said, has purchased other items from eBay, and this company has worked on their behalf for a long time to assist in getting their items shipped to their country).
So it appears I am right- that the purchase was made by this buyer from whatever Spanish speaking country he is from, via whatever eBay site he purchased it through. Then what I see in the transaction details in Paypal, is the buyer has his first and last name, and the shipping address of Enkarga in Doral FL.
Somehow, there must have been a glitch in the system from his eBay site to ours, where he was able to make the purchase and pay for it via Paypal, without it showing up in our eBay system.
Maybe I wont get charged any final value fees then??? Who knows.
