Just bought two Nokia 800 Lumia the last two days in tesco.
Spend £30 instore and £15 off phone making payment of £115 each phone.
Had to buy some beer,wine and boxes of biscuits for christmas presents.
Using Giffgaff in both phones. My boys have sony experia s but for my wife and myself for text ,e-mail, internet and facebook this is spot on. May not be for everybody but in my opinion good deal.
