Co-mail Confusion: Do You Know How Much You’re Really Saving?

Your job is to figure out your true savings—the difference between what you currently pay and what they are proposing.

Finding out what you currently pay is the easy part. After every mailing, the USPS gives you a receipt called Form 3541 (3206 for nonprofits). If you mail versions, each version of your magazine gets a 3541, so each mailing may have many pages.
