Rich, how far in advance can I change the shipping address if I order the physical book? My living situation is very uncertain right now, and I have no idea if I will be in my current location by the time August comes around. I very much want to order the physical book, but I'm worried about problems with shipping if I end up having to move.*

*I know the obvious solution to this is to just pre-order the PDF, but I prefer the physical books for a variety of reasons.
