Lesson packets range in weight, but a standard lesson requires the 2-ounce postage rate. We recommend purchasing 2-ounce stamps from your local post office. A lesson that includes several additional inserts (multiple Roadmaps, notes from Crossroads to a student, additional pages to your letter, etc.) may require the 3-ounce postage rate.
A single “Forever” stamp is not enough postage for any lesson packet.
If there is not enough postage on an envelope, the packet will be rejected by the student’s facility and returned to the Crossroads office, resulting in a delay of 2–3 weeks before the student gets the lesson.
You can have a lesson packet weighed at your local post office if you are unsure of how much postage to use.
