If you already have an Orange mobile you can get Unlimited 20-meg Broadband for £7.50 a month on an 18 month contract. The first 3 months are free and you can get an additional £100 cashback if you go through Quidco. This makes the price £12.50 for the full 18 months. That's not £12.50 per month but £12.50 for the full 18 months, i.e. 69.5p per month. In addition to this you get a free N rated Router which is a Netgear N150 which is worth £40. You also need to switch your phone rental from BT to Orange but the phone rental with Orange is only £11.50 per month which is cheaper than BT.
