I give away a Kindle Fire 7" (8GB) in the winner's choice of colour EVERY MONTH.
The only catch? You have to be a current subscriber to my author newsletter*. I send out an email once a week, telling you about my and author friends' new releases, discount deals and more.
You can see examples of previous newsletters in my Archive here.
*Well, you have to actually enter the draw as well. No purchases are EVER necessary. Draws are run though Rafflecopter and winners are selected entirely at random. Yes, I do ship internationally :D
