This is a good deal if you go via quidco and cash back via redemption.
I've been doing redemption deals for ever and never once had an issue, can't comment on mobiles.co.uk but if you follow some simple rules when claiming cash back, you can't go wrong. Anyway here is the deal.
600mins, 500 txt, Blackberry email & unlimited data*
11 months line rental free via redemption, £35/month + quidco £50
£35 x 7 = £245 - £50 = £195 over 18 months £10.83 per month!!!!
You can get the hand set for about £160 PAYG so for an extra £35 you can have 18 months worth of calls/txt/ data not to be sniffed at.
If anyone can find a similar deal on 12/18 month contract for the Bold 9700 let me know, the 8520 is for the Mrs :)
