If the mail volume keeps dropping, postal workers will be laid off, and postage rates may rise. The USPS has already been forced to consolidate mail carrier routes. So how do we pump up the volume without spending any money? Easy. When you get junk mail, such as credit card offers, car loan offers, magazine offers, or other things that have a self-addressed to the company envelope, with “no postage required” on the envelope, simply stuff all the solicitation materials back into that envelope (without signing anything, of course) and seal it and pop it back in the mail. The post office gets paid for delivering it. I do this nearly every day. I have not noticed any of these companies taking me off their junk mail list yet.
