I'm no stranger to selling items, both on here and via Gumtree. I am well aware of the potential risks, and generally advertise items as cash on collection only, especially where Gumtree is concerned. I'm first to admit that I'm perhaps a little odd, but I do find other people strange and difficult to understand. I'm selling a rather expensive pair of Genelec studio monitors. They're advertised as cash on collection from me only. That way the buyer can see them, and hear and test them
