If for some reason you can't pick up the book locally you can always set up a subscription online here:
http://www.mycomicshop.com/subscriptionservice/
Me and my fiancee used to work there so I can guarantee good service. They even ship overseas for those who are interested.
But I don't wan't to be biased. There are lots of other places to order online as well and I would only place an order online if your local retailer just refuses to order you a copy out of Preveiws for you…(which is pretty dumb, that's what they are there for)



Just FYI.
