Got some rather funny pm when I tried to sell off my stuffs a while ago.
His agruement is : "2nd hand shop are selling at $XXX so you must sell lower than them"
However, the last time I neg with a seller and his arguement is "Normally shop dun take care of the product as well as me. Therefore, my lens should sell at or above price in the shop"
Which arguement do you belive in?
