We mail our posters out in tubes, and, because of the long shape of the tube, the USPS may not deliver to your door or wherever you usually receive your USPS mail. Instead, a “you have a package waiting for you” slip may show up in your mailbox. After a certain amount of time, if they are not retrieved at the post office, they are “returned to sender” and end up back in Glover. So if you ordered a poster, be on the lookout for the tube, or a notice that you have a package.
