I like giving the seller the benefit of the doubt, not everyone can be on their a game everyday.
Honestly while eBay was a nuisance it understandable why it’s set up this way. I was on the other side of this where we shipped a thing and the buyer claimed it never arrived. Which we later proved it did. And considering how rare or hard to find some items are it’s a good service.
That said I support local sellers in my area before I check eBay. Then eBay but local to my country, the international if the price is right.
