Reposted from another forum, I've just done it and it works! Personalised Cards| Birthday Card| Card Greeting| Photo Greetings Cards must be worth £2.99 or less and it includes free delivery. You don't even have to put your card details in just choose design of your card, edit text and put delivery details in. When you come to the checkout use Promotional code FUNKYFREE and you will see the balance to pay is now nothing.
SWEEEETTT!! Cheers for that - I got cheeky and tried for an itunes voucher for free but it wanted me to pay for that haha bastards
