Understandable. I’d make contact with the buyer and you can generally flush out an obvious scammer that way. Clearly
Some will just come across as perfectly legitimate and still steal from you, i’m Afraid that’s the risk with eBay
I’ve bought a watch from eBay for more than £3k before so genuine buyers are out there lol! Like I say, get in touch and see what happens. Always trust your gut instinct.
