I Don't Want to Be Late, I'm Waiting at the Gate

Here's a question about how to maybe save a little money. Committee Member #3 says I shouldn't spend the money to send any applications by anything but regular mail. Obviously, I wouldn't bother with fast mail for "postmarked by" deadlines, but he says it even for "received by" deadlines. Even when the "received by" deadlines are, like, tomorrow.

I mean, I know no one's really gong to start looking at applications until December, so there really is no reason to spend the money on the fast mail. But still, it really feels like I ought to get stuff in by the deadline. No?
