Selling high priced items?

I have a listing of a coach bag on FB marketplace but with shipping and 10% seller fee, the buyer was asking if I had Vinted and if I could sell it to her on there.

Would this be a bad idea? I’m selling it for $90 and I’m terrified of losing this bag and/or being out of the money if she tries to scam me.

Anybody sell higher priced items/ advice?
