Depending on where you got your code, you apply it in one of two places. See also the more detailed walk-through in How do I use a coupon?.

Stripe promotion code (checkout)

For percentage-off or fixed-amount promo codes (for example, from a marketing campaign):

1. Open the Plan page.
2. Click Subscribe on Pro or Organization.
3. On the Stripe checkout screen, click Add promotion code.
4. Enter your code and complete checkout.

The discount appears on your first invoice (or each renewal, depending on the code).

Partner program code (Offer page)

For partner programs like Legatus or OLPA that unlock free Pro access:

1. Visit your partner-specific landing page (e.g. magisterium.com/offer/legatus) or the general redemption page at magisterium.com/offer/general.
2. Sign in or create your account.
3. Enter your code in Coupon Code and submit.
4. Your account is upgraded immediately.

Code didn't work?

• Check the code is typed correctly (codes are normalised to upper-case before matching).
• A Stripe promo code only works at checkout, not on the Offer page.
• A partner code only works on the Offer page, not at Stripe checkout.
• If you're already on a paid plan, not all Stripe codes apply to existing subscriptions.
