You're absolutely right if its a stranger, I'll laugh at them for overpaying. But if its somebody I know or a friend I will absolutely say not to buy it the price is far too high right in front of the seller. I have done it before, mainly when helping freinds buy cars, bikes or trailers. And if you haven't noticed most of the gun buyers here are not strangers to me and are friends so therefore once again, yes I'd do the same thing in person as I'd do here
