Complaint / review text:
I regularly order books (for a group I'm involved in), and I've used the Barnes & Noble allegedly same-day delivery to Manhattan if you order early enough in the day. Maybe half the time the books arrive on the same day; sometimes takes up to 4 days. The latest time, it took 4 days, and B&N kept telling me that the books had been shipped and would be received "today" or sometimes "tomorrow"- promises that didn't pan out.
Suggestion: if you need a book by a specific deadline and you live in Manhattan, try Amazon.com.
