Kobo's got some sort of odd 'let's find out more about you' thingo going on now. You access it from the home page on kobobooks.com (see the countries applicable in the Fine print section)
It's called 'Who is your Literary Alter Ego?' and to enter you run a short video and answer questions like: what is your favourite .... and then you choose from one of the images in that group. I chose not to answer any of these and it auto went through them all and at the end it decided that I was like Atticus Finch!!
Woot woot because as I say I did not answer any questions!!!
Anyway the 30% code one gets for being part of this strange event is:
alterego30
