For those of you who were having trouble with the code not applying. The way I finally got it to work for me was going to Kobo site, clicking on 'my account', then click on 'payment information', then select 'Home' from there and start shopping after that. It's worked for me every single time I do this.
Not going to question why, just know it did work!
Hope it helps someone else. Happy shopping til Oct 15!
