Simply add the item to your basket, use the promo code "DONGLEDEAL" for £10 off, then then go via QuidCo for a further £11 back.http://www.quidco.com/3-mobile/
For anyone having problems with the Discount Code and Quidco dont worry read this if you've put through the Discount Code and Quidco and the order appears at £29.35 Via your Email.
The Discount Code goes through with a seperate order web reference Number, When you receive an email confirming your order you'll get a different order referance with the total acting as £29.35, However this does not include the information of the Discount Code. DONT WORRY The codes gone through but has not shown up on the Email. If you have any douts of it going through Call 3 on the Number provided on the email. The lady i spoke to said when you receive your pack it'll contain the referances of the discount. I hope Quidco Pays out!
