Something like that happened to me, but with a NYX #3 and a Batman (52) #1. Sorry that happened to you. More and more of this swapping is going around.
Same thing happened to a friend of mine,a while back but he got his money back from Paypal.
He sold a raw Deadpool 1 for about a $100, the buyer messaged him and said the book arrived damaged.The buyer sent back a beater VG copy of Deadpool #1.
The buyer apparent;ly went on a crime spree and pulled simiiar scams with other sellers as he was suspended.Eventually, my friend got his $100 back.
Point being, Paypal has been changing up their policies on seller protection lately.
I tried to put out a warning about this, but to many people couldn't comprehend.
Here is proof that the comics were swapped out, eBay didn't seem to care. This is only one of the many that were like this...
