If you mean the manga, then you could find it at a general bookstore, like Borders, Barnes & Noble, Waldenbooks, etc. You would probably have higher chances with an online store, like RightStuf, Amazon, etc. Or if you feel lazy, just read it online.
If you mean a DVD, there are too many things "vol 1" could mean.
