<p>i'm sending some supplementary materials, but it won't be postmarked until january 3rd because the post offices are closed tomorrow...do you think the universities will still accept them? i already submitted all my applications online</p>
<p>Yes - send it with express shipping just to be safe. But remember, as I've said in numerous other threads, there are post offices located outside airport facilities that are open 24/7 no matter what holiday is going on. Look it up. You could even send it tonight!</p>
