Okay please don't let this be an error but it looks like all Agency Publishers are couponable!
I am in serious trouble! S&S books are now couponable. Now we just need a trivia game and some of our Code Angels to help us.
Oh I would wait a bit as Kobo will start marking the new couponable ones down I think here shortly. I notice Penguin and Random House are already being mark down to compete with Amazon.
