Not sure if I’m contacting correct place: I’ve collected copyrighted 1951 Nancy Drew Mystery Stories book “The clue of the Black Keys” hard back book. In the back of the book there is an ordering page for other books w/the post office PO Box # of yours. I’m only interested in finding more about this particular book. Can you help?


They started delivering our mail (10009) when the post office on East 14 was closed. Since then, mail delivery has been uniformly terrible. Mail generally arrives late in the day and sometimes not at all. Don't bother calling because they never answer the phone. The problem, I suspect, is that they consolidated the 14th Street PO with the larger facility in Murray Hill.


This post office will "prompt" you to use the "automated" express kiosk for payment with debit or credit, but if you pay for express, (next day), your parcel won't get there next day. I'm asking for a refund, cause my flat express envelope was accepted at 4:05pm, on 2/26/14, and the girl said it would get there next day. It's still at the post office in the town my neice lives in, just upstate, and still isn't out for delivery today, 2/28/14 @ 9am. Oh, just got an email just now, that it's out for delivery @ 9:10am. So it looks like the email arrives 1.5hrs after any update; in my opinion, it should be instantaneous, like gps, or stocks. Humfff.
