I know a lot of people out there will vote code - I will just have to accept that, but here is the deal anyway:
I have one contract with vodafone where we spend approx £20 a month, phoned up to enquire about adding an iphone line as well and they promptly offered the iphone 4 for £30 a month and £110 upfront. I went on to tell them a lot of the cash back sites offered £100, although we agreed it was not guaranteed the customer advisor spoke to a manager and they matched the £100 off so I got it for £69.
I know they are customer specific, but apart from paying my bill on time we really don't spend much money with them. I just wanted to let people know it looks like they may be doing quite good deals before Christmas and the new iphone 5.
Hope it helps some one
