Mail Packages

<p>I'm buying a book online and having it shipped to my UCSD address, but it can arrive either before or after January 3rd (packages are not accepted until 1/03, Monday). Will it go back to the post office or sender if it arrives early (since nobody will be working during break)?</p>

<p>If so, I can have it sent to my home address.</p>

<p>I am also curious about this. I’m thinking of ordering a textbook with an estimated shipping of 2-9 days, but don’t know if I should…</p>
