O2 are offering a deal in store for £13.50 a month 24 month contract for 100 mins/ 100 texts and 100mb. Free iPhone 4 8gb. Not a great deal but if your phone is broke or not really wanting to pay extortionate costs for insurance not a bad price for a backup, give the sim to your grandma or someone else who will use it sparingly and get a giffgaff sim.
Know not a great tariff but forget the tariff think of how cheap it is for the phone if you can't afford to buy it outright. This was I store at 02/ just ask I store for the deal.
Be kind and gentle with the remarks
Found it in blyth, Northumberland although the manager said it will be In store now if you ask.
