I just wanted to share something that I found. When I was searching Mobiles.co.uk, I found that they were selling an unlocked Tocco Lite on PAYG (Which comes with a compulsory £10 Vodaphone Top-Up) for £49.90. This of course comes to about £60. Quidco offers £10 on all PAYG phones despatched, so this brings it back down to £50.
Now if you take a trip down to CEX, they will pay £81 for an unlocked 'A' condition Tocco Lite. See where this is going?
A quick look on eBays completed listing for a Tocco Lite is also pleasing.
Hope this helps someone!
