If you are not interested in mobile cashback offers please stop reading now!!! I see Icejamin put up a very similar deal and it is freezing but someone may find this useful it is all down to personal preference.
I just got this phone on orange for 24 months 100 mins and unlimited texts plus 2 months free off peak data. £15 per month with 19 months free by cashback redemption from E2save who give £40 Quidco.
= 24 x £15 = £360 - 19 x £15 cashback (£285)
=£75 - £40 quidco
=£35 total for 24 months =£1.46 per month!!!
Even if the cashback claims fail or E2save go out of business £15 per month was the cheapest deal I could find for unlimited texts and my kids have been running up massive bills by going over their text limit so I am going to save a bunch whatever happens.
I will not be using the Samsung phone though, I got one of the LG Cookies on Orange for £77.67 from argos, so if I sell the phone on Ebay it will actually cost even less.
Don't forget you will need to go through Quidco to get the £40 http://www.quidco.com
Don't forget to ring Orange straight away and cancel the itemised billing or they charge an extra £1.50 a month.
E2save have changed their cashback timelimits to 60 days from Bill date which makes the cashback claims more manageable you just need a system and it is easy.
