Service review

by Cathryn Bartlett on 30/08/2012
Already sent an email expressing how pleased I was with the price and the delivery. I ordered one day and it was there first thing the next, couldn't believe it. The prices are the best we could find so to get top service too what more can you ask for. It was very personal too as I exchanged emails with Chris who came back to me immediately when I asked a question and was very friendly and professional. I would give an A+ rating.
