I got a marketing email saying "25% Off Gift Just for You" - curious to see what the final price would be I tried it with the item in my cart but I got an error saying the code had already expired! The email only arrived 19 minutes ago and the code is supposed to be unique. What's up with that?

I noticed the same thing, so it's definitely not just you.

I looked at my email as soon as it came in and got all excited! Chucked the Legendary Bundle straight in my cart , but yep, the code had already expired. It says it's supposed to be valid until 10th January, so it might just be an error with the code?

I had the same issue. I’m guessing it’ll probably be fixed soon (that’s pure, optimistic speculation on my part).
