I just pre-ordered. I was worried because we're moving soon, hopefully before December, and I'm not sure my address will be correct then. But Tina B from Oookodook helpfully let me know that it's easy to change addresses before they ship, if necessary:

"yes, just email me prior to shipping and I can go in and change it at any time. Make sure you put urgent on the subject line and address change as I get about 1000 emails in december."

(We're downsizing, but OOTS still gets space on the new bookshelf, next to LOTR and HHG...)
