The big independent bookstore in town here (Powells) - on their website they say which location the book is available at. They have three or four separate stores apart from their main one, and a warehouse that houses other books not on their shelves. As far as I know, they don't list books that 'could be ordered through them' - only books that are readily available.
The other, smaller independent bookstores in town don't have internet listings of the books in stock, and don't sell online. AFAIK.
A quick call to the bookstore, posing anonymously as an interested buyer, would probably let you know for sure. If you can pick it up today from them, then it's in stock. If you can get it from them in a week or more, then they'll have to order it.
Fun to see your book on their website, eh?
