Please use this option to purchase 12 months of Harbor and Sprout upfront through your charter school. Purchasing the charter option will issue 12 non-expiring credits redeemable for any units of choice from our library, either existing or upcoming. Upon purchase, you will receive an email with information about how to get the credits to the correct account (your own if you are purchasing for personal use, or if you are a curriculum purchaser for a charter school, this would be the family for whom you are purchasing). This allows you to benefit from subscription pricing without recurring payments. Please remember that charter schools must purchase one license for each family using the curriculum.
