Service review

by Derek Hibbert on 12/11/2014
The website is really easy to negotiate and I found the ordering process particularly easy to use. The order was delivered very quickly and, although I had specified a safe location for the delivery, it was left with a neighbour. Not a problem though as the weather was dreadful and the delivery driver probably thought it better to leave it next door than out in the rain. All in all, a very quick and efficient service that I will use again.
