Deal the first: Through the month of December, they're offering buy-one-get-one-free on their five launch titles. I already had Blackwood (which I'll write about as soon as Cybils season is over), so I bought the hell out of the other four. For the price of two! So that's cool.
See this blog post for more info.
Deal the second: They have a subscription service. As in, you can pay for a year's worth of books up front, and get a new book or two every month. I can't even handle how much I love that idea.
See this page for more info on that.
