application id question

<p>so I still haven't gotten mine and I submitted my application on the 31st...should I contact them or just wait? I'm not sure how long it is before I get it so I'm starting to get worried that my application didn't send or something.</p>

<p>I applied in the middle of October and just received mine in the mail today. I wouldn't be concerned.</p>
