I have sold a lot of high priced goods in good faith, no questions asked. I would surely comply if asked if I wanted the sale.
I think a current right now pic with name, date & time card attached is a good idea, a phone call if needed.
I have sold high dollar scopes, custom guns, but selling a 350 buck baseball glove on Instagram almost soured me on ever listing again. I was new, no feedback. The guy was demanding, I told him 3 or 4 times, only 72 of these made, I don't need you. Just to move the glove, I took 10 bucks off and made the deal.
