Thank you very much for the code, unfortunately it doesn't seem to be valid. Not sure if it's expired or just doesn't like my account, but thanks for sending it anyway. If you wanted to try with someone else then feel free. Also, your PM box is full.
Where do I type 'Adwords voucher' to claim? It may be that Google just doesn't want to give me one. I have several accounts for various purposes/companies, but all are registered to my address so may just be that.
