This happended to me a few years ago. I shipped no confirmation no ins. He claimed he never got it. I offered a refund he accepted I sent it he claimed he never got that. I have proof he got that, but he still drug me through the mud over it. It ended up a ding on my rep. That deal cost me twice. To this day I am sure he got the gun but no proof and I am positive he got the refund as I have proof. So I paid him to take my gun. Not saying that happened here, just saying now everything goes with delivery confirmation and I ask the buyer if they want ins. If they refuse, I make it clear it is their loss. I think my new policy will be the cost of ins is added into shipping automatically.
