Question on handling an unhappy buyer

[Chuckindenver]

to add to this thread,,
over the last few weeks iv been cleaning house so to speak, selling off a bit of my parts.
so, i sell a rare Lyman target sight for a Marlin 1893, fetches 120.00..thats a deal as iv seen them bring almost 400.00.
anyway, guy that gets it, emails me and says he wants his money back, says it was ground on,.whatever...he sends it back, i refund his paypal,..and relist it..this time showing with a Mic, all the lengths,, ect,,my rule is,,,if you cant read the sold as is with no guarantee, i block you from bidding...well the guy trys to bid again on the same sight,,and emails me and asks why??i said mostly cuz he,s a moron,, and move on.
flash foward to the second one, i sell a G43 sniper scope, very cloudy, and i show pics of it,,lots of em,,guy gets it for less then 300.00 , emails me and says,,hey,,,its cloudy,.. really? duuuh,.send it back..ill sell it again...he says, howbout a little moneys back...nope...send it back, ill have it fixed, and then it will bring 500.00 like it should, and it wont cost me more then 75.00 to have the lens fixed..
so, its not a one time deal, they are everyplace......
