Selling 600 posters one at a time means 600 closed sales a month. It means 600 amateurs who didn&#x27;t proof their own work. It means filling 600 tubes, attaching 600 labels, and posting 600 packages...every month.<p>It&#x27;s possible. Whether it&#x27;s worth it or not is another matter that depends on what other options a person has.<p>Good luck.
