Take it up with PayPal, no item, no money.
Also found a weird listing for some Nike shoes, after searching Paypal on eBay:
SOLD! Nike Air Foamposite pearlized pink $180 paypal shipped jordan kd kobe
For sale is a pair of Nike Air Foamposite pearlized pink size 10 condition 9/10 no flaws execpt slight little yellowing not really that noticeable. Will sell these for $180 shipped through paypal invoice so hit me up if you tryna buy them.
Are they listing things and doing transactions outside of eBay? Hmmm...
It looks like a lot of people are trying to sell shoes this way.
I did just do a transaction off of eBay through Paypal
I got some broken Invader Zim figures, I bought a lot of stuff the legit way and the seller had some that were not included because they were broken.

(Minus the Zim in picture 2)
