It sounds like you have a nicer independent bookseller in your area, Rainypark.
One in my area was quoted in the newspaper as saying he had only ordered 4 copies but probably should have planned on a few more since other stores were selling out, but it wasn't the type of book his clientele would be interested in.
He also ventured to add that maybe Harry was the one killed off in Book 5, and then Ms. Rowling would surprise everyone by not writing any more.
Some people may enjoy his cynicism ... but I get rather tired of living in the midst of it day after day ... at least I don't work in that "hip" area any more.
My copy is coming from England, but I'm not in a hurry because I still have a little catching up to do (in my free time, when I'm not watching Dorian Gray, The Innocents, Eye of the Devil, or DS 1970 PT) ....
Sadly unhip,
Vlad
