Use code USW08 for speaker
One of the worst call plans around, but for £336 (after claiming all the cashback) you get the Xperia Z1 compact and the Sony SRS-BTM8B Portable Speaker.
£30 is available via quidco too or £31.50 via tcb, but tcb has no mention of the speaker offer so may be declined. So it could be as little as £306 if all goes well.
Vodafone £14.00 per month (Includes £300 cashback reducing the monthly line rental from £26.50 to £14.00)
+ 100 Minutes
+ Unlimited Texts
+ 100 MB Mobile Internet
+ 24 Month Contract
Not particularly keen on cashback by redemption offers but mobilephonedirect allow you to claim online rather than the usual by post method.
