On Quidco - Cashback is £12 for Pay As You Go Mobile on "Three Store"
Absolute bargain at this price but I'm not sure about the delivery costs for Three (if you know how much delivery costs then please tell me). If delivery isn't free, then there are vouchers for free delivery online.
100 mins, 3000 texts, 500MB Internet included for only 30 days, and will continue every month if you top up £10 each month.
