Another word of note, i would totally disagree with Sickly Sweet … Another word of note, i would totally disagree with Sickly Sweet unfortunately as I have had 2 contracts in the past with different companies that both offered cashback. I played by their rules and both companies went bust before I could obtain all my cashback for the deal. IMHO much better to have a contract with less line rental that slightly more expensive contract with the 'offer' of cashback.
