LPT: Don't throw your junk mail away. Use it to to help the USPS instead!
Next time you get a credit card offer in the mail, or a junk piece of mail that includes a prepaid envelope or postcard, don't throw it away! Send the envelope back with a blank sheet of paper inside, or don't fill the postcard out, but still send it back. The company that sent it to you had to pay the USPS for postage on each one they get back. This is a way to support the USPS by doing very little, and sticking it to the annoying companies that want all of your money.
In the 90s we would send companies “hate mail” by stuffing prepaid envelopes with things like ‘blanks’ (flat heavy metal pieces), a roofing shingle) and layers of other competitors’ mail or junk news. This is because the company would have to pay more upon recieving the junk mail. It eats into them. It actually somewhat reduced our junk mail returnables, I think.
Send that mail y’all.
