<p>where is the nearest post office? i just sold a book online and need to ship it. where can i do this?</p>
<p>Inside the basement of the Union, there's a packaging/shipping store for one of the major companies. If they can't do what you want, there's a post office on Liberty between 5th and 4th avenue, open M-F 7:30AM-7PM</p>
<p>There's a post office on South U located inside some sort of mall type thing.</p>
<p>The post office on South U is in the same building as the Starbucks. It will be probably be cheaper than the packaging store in the Union.</p>
