Priority mail isn't guaranteed. It's supposed to be delivered within 2-3 days or whatever, but it can just as easily be delivered in 6 weeks, or not at all. I know from personal experience and the experiences of my friends and family.
Express mail is guaranteed, but why waste the money at all? Just send it by regular mail and call a week later to see if it arrived. If you want delivery confirmation, the post office can do that for about $0.50.
Yeah, first class with delivery confirmation is generally reasonably fast on the same coast (South to New England ~ 3 days; within 100 miles, generally 1 day). I don't know about first class coast-to-coast, maybe a week or so, but Priority Mail is usually about 2-3 for coast-to-coast. Of course, neither is guaranteed, but mail service is much more reliable than people give it credit for [see exception below].
If you print shipping labels using USPS software, you don't even have to pay extra for delivery confirmation for Priority Mail (there is a small charge for first class--13 cents-ish).
Of course...as long as you don't use the Post Office at 06520, your mail will arrive reasonably fast.

And if you're sending mail from that post office, don't drop it in the slot inside the post office; instead use the blue boxes out on Elm Street.
