Sorry about that - I've fixed it now :)
I think I guessed the closing date when I posted it, as I couldn't find any T&Cs. After reading your comment I went back and checked and noticed that they've posted them now in the 'Notes' section, with a closing date of 13th November.
Where did you get the closing date of 27/10/2017 from? I looked but couldn't find one, which is always frustrating.
