I now think there is something going wrong at Kobo... I've just won another Aura H2O.
I know of another person who won one yesterday as well.
Both of mine were won in the US, the other persons was the UK.
While I think it would be pretty amazing to win 2 of them, I am now expecting to get an email saying theres been a mistake and I wont be getting either of them.

Another thing I have just noticed: Both the emails I received after winning the prize have the subject title 'Your daily prize confirmation from Kobo's Best of 2014 Contest' but the From title say's 'Kobo's After Dark Stories Contest' which was last months contest. Although the actual email says 'Best of 2014 Trivia Contest'.
It will be interesting to see if Kobo honor the prizes or not.
