Sorry to say the lunatics (buyers) have taken over the asylum, and they believe they can get away with it.Selling on ebay is not a level playing field anymore, the buyers hold all the cards with a spare couple of aces up their sleeves courtesy of ebays new 6 month money back guarantee, it is a get out of jail free card.I have found over the years if a buyer is asking silly requests like you have received, exercise extreme caution, even to the extent of placing them on your banned list so they can't purchase, anyone waving a red flag at the start will undoubtedly turn out to be nutter.I had a case this year where a buyer kept on annoying me to reduce the price to her best offer, which was considerably lower than my listed best offer.Eventually she bought it, then 1 month after purchase and receipt, opened up a pay-pal dispute on the grounds the goods were not as described(the item condition was as stated in the listing), but all would be forgiven if I gave the buyer a refund, wait for it ! the amount would of reduced the purchase cost to the buyers lowest best offer ! Its a scammers paradise out there ! I'm waiting for the discussion boards to light up soon, with Dvd and Cd sales gone belly up and returned for full refund under the new policy, when we all know the buyers just bought the merchandise  dubbed the dvd/cd onto a blank and returned for the $$$.Take care !
