Same happened to me (after congratulating me that my code had been accepted) - although with the cash back/gifts it should all still be a 'good' deal.
Code worked for me, great deal thanks :)
That's rubbish for you, sorry - I guess we can't complain about these codes not working - this one worked for me on Grazia and Empire earlier.
Great offer thanks. I feel a tiny bit conned as the discount code said it had been accepted but when I went right through to the end and clicked confirm it said the code wasn't valid! Oh well it's still worth it.
