edit: Seems like people are confused.
Carphone warehouse are offering a FREE jabra bluetooth headset + an orange SIM CARD when you buy a £10 topup ALLOWANCE.
PLUS If you go via quidco, you get £3.
so total cost = £10 (for purchase of topup) less £3 (quidco) = £7
Now for £7 you are basically getting, an orange SIM CARD, £10 CREDIT ALLOWANCE for calls/sms, a FREE jabra bluetooth headset worth £14.99
also remember with orange you get 2 cinema tickets for the price of 1 on wednesdays!
edit if link is not working, go to carphonewarehouse website and then click on pay as you go sim cards on your left to see the offer
