I wish it was easy to get a copy of Scott Pilgrim volume 4, but it’s still kind of hard (and confusing). Here is my attempt to explain.
1. Good comic stores who ordered plenty of copies should still have copies. Examples of good comic stores: the Beguiling (Toronto), Strange Adventures (Halifax NS), Chapel Hill Comics (north carolina), Jim Hanley’s Universe, Midtown Comics and Rocketship (all NYC), Comix Experience and Comic Relief (both Bay Area California), Meltdown (Los Angeles), Gosh (London UK), Page 45 (Nottingham UK), many more that I can’t list. Obviously, not everyone lives in one of these cities. Some of these shops do mail-order and you could check the website of your closest one and find out.
2. Khepri.com probably has copies (if anyone knows, please inform me). They’re an online comic store. Here is another one: In Stock Trades dot com.
3. As far as I know, most of the Big Box Bookstores (Barnes & Noble, Borders, Chapters, Indigo, etc) do not have copies yet. If you work at one of these stores or corporations in a knowledgeable capacity, please inform me otherwise.
3a. I am told Borders ordered “several hundred” copies. Which would mean less than one book per store.
According to the post, 7000 copies are already in circulation.
