You go into the item from your my ebay page and select revise my listing.
You must change the part that says a buyer can arrange their own courier.
NEVER, EVER allow a buyer to arrange a courier as you are still totally responsible for getting the item to them.
If there is a problem you wont be able to sort it as you didnt arrange the courier yourself.
Also, collected items you should say cash on collection preferred. You cannot refuse paypal but its very unsafe for collected items as you cannot prove delivery on-line.
Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.
