It's a problem in other cities as well, not just Augusta. A lot of Maine post offices are short-staffed and have generally been suffering over the past several months.

The best thing you can do is use USPS's Informed Delivery service. It'll tell you what mail is coming on each day. The only problem is that sometimes we'll see what mail is coming and it'll come a day or two later, but a lot of it is junk and shit. Still, it's a good tool to keep tabs on your mail. Easy to sign up, too.
