Seller's responsible to get the buyer their item, period. If the buyer wants insurance, they pay for it, IMHO. Been buying, selling, shipping for 25+ years and have never lost a package yet, knock on wood.
I try my best to package securely, but I've seen some stupid stuff over the years. Just recently had a dipshit ship a Holosun red dot mounted on an aftermarket mount that wouldn't fit back in the factory box with the mount attached loose in a USPS flate rate envelope. The factory box from Holosun is similar to a Pelican case and is bomb proof.
Would've taken two minutes to remove the four mount screws and put the optic inside the case. Instead it bounced around clear across the country banging into the hard plastic case (yes, the case was in the envelope). No bubble wrap, nothing, on the optic.
Had a guy ship a rifle once wrapped in a blanket. That was it. No box. Nothing. Duck taped blanket.
