I bought a large hifi cabinet/sideboard from an auction house in Devon.
I found uShip through google and put in a bid for transportation.
The transporter I accepted a bid from was marvellous, kept me informed, delivered on time and transported the furniture safely.
Do check uShip fees though - they were added on to the quote by uShip when it was accepted and I went to pay!
Otherwise, a handy site.
