Get the Nokia 1800 on vodafone from OneStopPhoneShop for only £10.01 including the airtime. Buy through TCB and receive £7.57 back (or £7.50 through Quidco). Making the cost £2.44 then.......
Keep your sim with the credit (£10) and sell the phone to TopDollarMobile for £6.50 (or phonebank £6.00) and they can pay direct in your bank or by cheque if you dont like putting bank details in.
Therefore making you a profit of £4.06 and a free orange sim with £10 credit.
Hope you find this useful.
