I think all you've got to do to get the book is to order $19 + in merchandise. I didn't have to add any special coupon or anything when I ordered.
BTW I love the book! It's a smaller format than I expected, but all the better to haul around with me! Chris is a smart ass, but isn't he always? Better a smart ass than just an ass I always say.
Only one thing I didn't like was that the only teas mentioned were the teas available through Adagio. I suppose that's because it was published by Adagio, and written by an Adagio employee. But it tends to lend a bit of a marketing gimmiky feel to it. It's still a lovely book! The pictures are spectacular, and the informaton is wonderful, but it feels a little (a very little) like a giant sales pamphlet.
I'm certainly not sorry to have it though, and I do recomend it!
