Having had experience using the fourthirds site to sell my E-3. I think you should be clear about the price and the shipping or exchange from the seller to the buyer. I live in Toronto and I advertised as selling to someone in the greater Toronto area, ended up selling to a chap in the States and what a rigmarole that was for him to take delivery because I said at the start that it had to be picked up at my house. These are important things to remember because the seller wants to recoup as much of his investment without any extra expenses for shipping. The sales was ultimately successful!
