Like I said, we are arguing different things as I am not arguing neither of those points.
I do think that sellers should have the option to protect themselves for an item but that several take advantage of the Buyer protection requirements to charge absurd amounts to overseas buyers taking advantage of the situation for their own benefit at someone else's expense. Often these sellers don't honor the shipping cost they charge and send you the item at a much lesser cost than what you paid for - The gun seller seems like one of those.
I also believe that friendliness and accessibility to a wider market can benefit the seller just as much as the buyer. Several successful US sellers have proven that since they are highly regarded, in good business and with glowing feedback. Therefore it's also possible to charge a fair amount in shipping cost and still benefit regardless of Paypal buyer protection. I was recently quoted by one of these good US sellers that they will ship me a similar small gun for only $7.50
Now that this is settled and both our perspectives are now well documented, there is no need to continue derailing your own thread trying to score points.
