Iv given up on DD, iv had good experiences with Adverts. The users are generally rated good or bad so it cuts out a lot of A holes.
I recently bought a classic car and have sold a load of stuff, cars, motorbike, tools, building materials, all sorts of everything.
Facebook market place is very handy, a lot of UK sellers but a lot of Irish aswell. That said iv only really been window shopping on it.
