So when when do knives get lost in the mail? For what reason? If the address was wrong (tracking proves that now) the seller would be or the buyer?.. if they gave the wrong addrees or street number (typos) or their address is an old address listed on their Paypal and is different from there new residence they just moved to (happens more than you think). Also what if the knife is considered illegal in the location the buyer is located the knife is confiscated and not returned to the buyer? (examples would be elephant ivory without paperwork, automatic knives, blade length) .The buyer should know their laws in their jurisdiction . If a box is shipped empty (like someone suggested) then that seller would not be here long anyway. He is a thief. Same goes with not giving full discloser on condition of a knife or if the knife is misrepresented. I don't think this thread about who is trying to cheat someone but somehow people have turned it into that.
Coming from my experience here. All the high end sales I have made the seller asks for the extra insurance and offers to pay for it. I think that anyone buying a $500. $1000., $2500. knife would naturally ask that question if they are making a purchase from a private seller since the extra costs beyond the deal is quite a bit of extra money.
I have made quite a bit of deals here and dealing with regulars this seems to be quite obvious. Take my advice and always ask the seller about insurance on a high end knife if you want that extra comfort level. I would.
Packages get lost all the time for one reason or another. I'd hazard a guess that 9x out of 10 it's the fault of the shipper: improper packaging, not enough tape, smudging an address or typing it in wrong, trying to cheap out on envelops or boxes (i.e., trying to cram a large, heavy item into a document mailer because it's cheaper), etc....
The rest of the time, it could be any number of reasons on the shipping company's side: improper or rough handling of the package, misplacing the package, the package fell off the truck or got damaged in a sorting machine, or maybe it was just outright stolen, etc...
On the rare occasion that it might be the BUYER'S responsibility, I.E., they forget to update their paypal address and it never gets forwarded or returned to the seller for whatever reason, or they send the seller the wrong address altogether, then that package is not really "lost", it was just delivered where the buyer had specified, and I'm not sure anybody on here would argue that the seller should eat the costs. Same for when trying to order and ship something into your country that you know (or SHOULD know) is probably not going to make it through customs. I would think that most buyers realize that they are responsible for things like duty fees and whether or not they can legally obtain what they are trying to purchase.
At the end of the day, if I buy ANYTHING and the item doesn't arrive for ANY reason other than my own negligence in updating an address in PayPal, then I'm expecting a refund. If the seller refuses, I'm filing a claim with PayPal, and 99% of time, I'm going to win that claim. THAT is my extra comfort level. PayPal terms of service for buyers and sellers are pretty clear, as is the insurance agreement that you sign when you mail a package.
