How much do you think you would have paid in fees if you sold them in a B&M auction, how many people would even know you were selling if you advertised it in the local newspaper? How much do you think you would get for it at a garage sale? When I list something I decide what the minimum profit I want is then I add 15% to cover the fees, if it goes for more then I am still geting more than 85c from each extra dollar.
