if you go through to Phones 4U via Quidco you can buy a PAYG Nokia 2610 for £9.95. You have to buy a £10.00 airtime voucher but Quidco will pay out £10.00 for completed transactions. Effectively making the handset -5p! Flog both on Ebay for a quick profit!
(first post so be gentle!)
dont forget to go via quidco to get the cashback!
