OK this is a bit risky but for anyone willing to take the plunge it could pay handsomely.
e2save have an Orange Canary contract going at 99p (you have to send in your bill at various monthly intervals to claim which is where the risk is). The handset you get free is only a Nokia 1800 but if you've already got a phone then you can just flog it on ebay and use your SIM.
Providing the cashback comes through you've got 400 mins plus unlimited texts for two years for just under £24! Never used e2save before so if anyone has any comments please feel free to leave them.
Plus £65 cashback via Quidco if tracked (thanks mikeleeds )
