Just for reference, this is the deal from before http://www.hotukdeals.com/item/674966/nokia-5230-mobile-phone-on-vodafone
With the £6.50 possible cashback from QUIDCO this brings it in under £60
Personally I prefered the white one after seeing it (and yes, missing out on the ASDA deal)
Yes, you have to buy a £10 top up with it, but what are you going to do with a phone with no monies on it anyway.
Answer... loads, this phones plays music, takes photos and has GPS, all without the need of the cash in your pocket. If you don't think that free GPS is a good deal, get lost!
However I can't understate the importance of having money on you're phone, otherwise you can only call 999 and 112; thats no fun, because they're busy people, even if you have the time to call them. Don't do it HUKDers.
By a phone with credit, save a life, you know its the right thing to do.
