I've been in the market for a contract. I was speaking to CS earlier and was given this code if I were to go ahead and place order.
"The code is BT20030723.. Please take this code down and enter this code in the 5th screen of shopping that is titled as ORDER CONFIRMATION screen. You will be prompted with a text box which is labelled as If you have a promotional code enter it here."
Don't forget to go through quidco for a whopping £100!
