What it says in the description!
Need to replace my wife's contract which is running out soon and this looks like the best deal I can find at the minute - effectively £8.33/month over the year (A much better deal than the £10 sim only deal that's red hot at the minute!).
£35 per month outlay, but with 8 months cashback (on redemption) and £40 QC, works out £8.33pm. Even without the QC it comes in at just £11.67/month
Avoid if you don't like cashback redemptions. I've been stung once when CoolNewMobiles went to the wall, but this is backed by CarphoneWarehouse so a much safer risk. [I've had 4 other years - for both me & my wife - of completely free mobile contracts for those who are doubters]
Don't seem to be able to link to the deal direct, so select 12months Vodafone deals - it should be the top one.
There's an identical deal for the LG Cookie, but reviews I've read seem to favour the Samsung.
